Additional flags to control the allocation of a buffer

Implementations

impl BufferPoolAcquireFlags[−]

pub const KEY_UNIT: BufferPoolAcquireFlags[−][−]

buffer is keyframe

pub const DONTWAIT: BufferPoolAcquireFlags[−][−]

when the bufferpool is empty, acquire_buffer will by default block until a buffer is released into the pool again. Setting this flag makes acquire_buffer return FlowReturn::Eos instead of blocking.

pub const DISCONT: BufferPoolAcquireFlags[−][−]

buffer is discont

pub const fn empty() -> BufferPoolAcquireFlags[−]

Returns an empty set of flags

pub const fn all() -> BufferPoolAcquireFlags[−]

Returns the set containing all flags.

pub const fn bits(&self) -> u32[−]

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<BufferPoolAcquireFlags>[−]

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> BufferPoolAcquireFlags[−]

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> BufferPoolAcquireFlags[−]

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool[−]

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool[−]

Returns true if all flags are currently set.

pub const fn intersects(&self, other: BufferPoolAcquireFlags) -> bool[−]

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: BufferPoolAcquireFlags) -> bool[−]

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: BufferPoolAcquireFlags)[−]

Inserts the specified flags in-place.

pub fn remove(&mut self, other: BufferPoolAcquireFlags)[−]

Removes the specified flags in-place.

pub fn toggle(&mut self, other: BufferPoolAcquireFlags)[−]

Toggles the specified flags in-place.

pub fn set(&mut self, other: BufferPoolAcquireFlags, value: bool)[−]

Inserts or removes the specified flags depending on the passed value.
