Errors that are returned by bluetooth.gatt2.* methods.

The values correspond with those in Bluetooth 5.2 Vol. 3 Part G Table 3.4, and Supplement to the Bluetooth Core Specification v9 Part B Table 1.1, but this is for ease of reference only. Clients should not rely on these values remaining constant. Omitted values from the spec are handled internally and will not be returned to clients.

Only certain errors can be returned by LocalService methods. Those are noted in comments.

Variants

InvalidHandle = 1

The attribute indicated by the handle is invalid. It may have been removed.

This may be returned by a LocalService method.

ReadNotPermitted = 2

This attribute is not readable.

WriteNotPermitted = 3

This attribute is not writable.

InvalidPdu = 4

Indicates that the response received from the server was invalid.

InsufficientAuthentication = 5

This attribute requires authentication, but the client is not authenticated.

InvalidOffset = 7

Indicates that the offset used in a read or write request exceeds the bounds of the value.

This may be returned by a LocalService method.

InsufficientAuthorization = 8

This attribute requires authorization, but the client is not authorized.

InsufficientEncryptionKeySize = 12

This attribute requires a connection encrypted by a larger encryption key.

InvalidAttributeValueLength = 13

Indicates that the value given in a write request would exceed the maximum length allowed for the destionation characteristic or descriptor.

This may be returned by a LocalService method.

UnlikelyError = 14

A general error occurred that can not be classified as one of the more specific errors.

This may be returned by a LocalService method.

InsufficientEncryption = 15

This attribute requires encryption, but the connection is not encrypted.

InsufficientResources = 17

The server had insufficient resources to complete the task.

This may be returned by a LocalService method.

ValueNotAllowed = 19

The value was not allowed.

This may be returned by a LocalService method.

ApplicationError80 = 128

Application Errors. The uses of these are specified at the application level.

These may all be returned by a LocalService method.

ApplicationError81 = 129

ApplicationError9E = 158

ApplicationError9F = 159

WriteRequestRejected = 252

Write request was rejected at the profile or service level.

CccDescriptorImproperlyConfigured = 253

The Client Characteristic Configuration Descriptor was improperly configured.

ProcedureAlreadyInProgress = 254

Profile or service procedure already in progress.

OutOfRange = 255

A value was out of range at the profile or service level.

InvalidParameters = 257

One or more of the FIDL call parameters are invalid. See the parameter documentation.

TooManyResults = 258

Indicates that more results were read than can fit in a FIDL response. Consider reading attributes individually.

Implementations

impl Error

pub fn from_primitive(prim: u32) -> Option<Self>

pub const fn into_primitive(self) -> u32

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict enums should not use is_unknown

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<Error, D> for Error

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl<D: ResourceDialect> Encode<Error, D> for Error

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Error

fn cmp(&self, other: &Error) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Error

fn partial_cmp(&self, other: &Error) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for Error

type Owned = Error

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for Error

type Borrowed<'a> = Error

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
