Struct MessageFlags 

pub struct MessageFlags(/* private fields */);

A compact bitfield of message flags.

Implementations

impl MessageFlags

pub const FIRST_IN_BATCH: u32

Flag: this message is the first element in a batch.

pub const LAST_IN_BATCH: u32

Flag: this message is the last element in a batch.

pub const DEGRADE_ALLOWED: u32

Flag: downstream may degrade this message (e.g., fast/low-precision path).

pub const fn empty() -> Self

Create an empty flag set.

pub const fn from_bits(bits: u32) -> Self

Construct from raw bits (advanced).

pub const fn bits(&self) -> &u32

Return the raw flag bits.

pub const fn with(self, bit: u32) -> Self

Set a flag bit.

pub const fn without(self, bit: u32) -> Self

Clear a flag bit.

pub const fn contains(self, bit: u32) -> bool

Check whether a flag bit is set.

pub const fn first_in_batch(self) -> Self

Return a copy with FIRST_IN_BATCH set.

pub const fn last_in_batch(self) -> Self

Return a copy with LAST_IN_BATCH set.

pub const fn allow_degrade(self) -> Self

Return a copy with DEGRADE_ALLOWED set.

pub const fn is_first(self) -> bool

true if FIRST_IN_BATCH is set.

pub const fn is_last(self) -> bool

true if LAST_IN_BATCH is set.

pub const fn can_degrade(self) -> bool

true if DEGRADE_ALLOWED is set.

Trait Implementations

impl Clone for MessageFlags

fn clone(&self) -> MessageFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageFlags

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

Formats the value using the given formatter.

impl PartialEq for MessageFlags

fn eq(&self, other: &MessageFlags) -> 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.
