Struct rustacuda::stream::StreamFlags

pub struct StreamFlags { /* fields omitted */ }

Bit flags for configuring a CUDA Stream.

Implementations

impl StreamFlags

pub const DEFAULT: StreamFlags

No flags set.

pub const NON_BLOCKING: StreamFlags

This stream does not synchronize with the NULL stream.

Note that the name is chosen to correspond to CUDA documentation, but is nevertheless misleading. All work within a single stream is ordered and asynchronous regardless of whether this flag is set. All streams in RustaCUDA may execute work concurrently, regardless of the flag. However, for legacy reasons, CUDA has a notion of a NULL stream, which is used as the default when no other stream is provided. Work on other streams may not be executed concurrently with work on the NULL stream unless this flag is set. Since RustaCUDA does not provide access to the NULL stream, this flag has no effect in most circumstances. However, it is recommended to use it anyway, as some other crate in this binary may be using the NULL stream directly.

pub const fn empty() -> StreamFlags

Returns an empty set of flags

pub const fn all() -> StreamFlags

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<StreamFlags>

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) -> StreamFlags

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

pub const unsafe fn from_bits_unchecked(bits: u32) -> StreamFlags

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: StreamFlags) -> bool

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

pub const fn contains(&self, other: StreamFlags) -> bool

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

pub fn insert(&mut self, other: StreamFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: StreamFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: StreamFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: StreamFlags, value: bool)

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