Enum fidl_fuchsia_diagnostics::StreamMode

#[repr(u8)]
pub enum StreamMode {
    Snapshot,
    SnapshotThenSubscribe,
    Subscribe,
}

Enum specifying the modes by which a user can connect to and stream diagnostics metrics.

Variants

Snapshot

The stream will serve a snapshot of the diagnostics data at the time of connection, then end.

SnapshotThenSubscribe

The stream will serve a snapshot of the diagnostics data at the time of connection, then subsequent calls to the stream will hang until new diagnostics data is available.

Subscribe

Calls to the stream will hang until new diagnostics data is available. Between calls to the stream, newly arrived data is buffered.

Implementations

impl StreamMode

pub fn from_primitive(prim: u8) -> Option<Self>

pub const fn into_primitive(self) -> u8

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict enums should not use is_unknown

Trait Implementations

impl Clone for StreamMode

fn clone(&self) -> StreamMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StreamMode

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

Formats the value using the given formatter.

impl Decodable for StreamMode

fn new_empty() -> Self

Creates a new value of this type with an “empty” representation.

fn decode( &mut self, decoder: &mut Decoder<'_>, offset: usize ) -> Result<(), Error>

Decodes an object of this type from the decoder’s buffers into self. Callers must ensure that offset is a multiple of Layout::inline_align, and that decoder.buf has room for reading Layout::inline_size bytes at offset.

impl Encodable for StreamMode

fn encode( &mut self, encoder: &mut Encoder<'_, '_>, offset: usize, recursion_depth: usize ) -> Result<(), Error>

Encode the object into the buffer. Any handles stored in the object are swapped for Handle::INVALID. Callers must ensure that offset is a multiple of Layout::inline_align, and that encoder.buf has room for writing Layout::inline_size bytes at offset.

impl Hash for StreamMode

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 Layout for StreamMode

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 the type’s alignment. Must be a multiple of inline_align.

fn supports_simple_copy() -> boolwhere Self: Sized,

Returns true iff the type can be encoded or decoded via simple copy.

impl Ord for StreamMode

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<StreamMode> for StreamMode

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<StreamMode> for StreamMode

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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