Struct AttributePermissions

pub struct AttributePermissions {
    pub read: Option<SecurityRequirements>,
    pub write: Option<SecurityRequirements>,
    pub update: Option<SecurityRequirements>,
    /* private fields */
}

Specifies the access permissions for a specific attribute value.

Fields

read: Option<SecurityRequirements>

Specifies whether an attribute has the read permission. If not present, the attribute value cannot be read. Otherwise, it can be read only if the permissions specified in the SecurityRequirements table are satisfied.

write: Option<SecurityRequirements>

Specifies whether an attribute has the write permission. If not present, the attribute value cannot be written. Otherwise, it can be written only if the permissions specified in the SecurityRequirements table are satisfied.

update: Option<SecurityRequirements>

Specifies the security requirements for a client to subscribe to notifications or indications on a characteristic. A characteristic’s support for notifications or indiciations is specified using the NOTIFY and INDICATE characteristic properties. If a local characteristic has one of these properties then this field must be present. Otherwise, this field must not be present.

This field is ignored for Descriptors.

Trait Implementations

impl Clone for AttributePermissions

fn clone(&self) -> AttributePermissions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttributePermissions

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

Formats the value using the given formatter.

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

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 Default for AttributePermissions

fn default() -> AttributePermissions

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<AttributePermissions, D> for &AttributePermissions

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 PartialEq for AttributePermissions

fn eq(&self, other: &AttributePermissions) -> 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 TypeMarker for AttributePermissions

type Owned = AttributePermissions

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 AttributePermissions

type Borrowed<'a> = &'a AttributePermissions

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.
