Struct ReadStages 

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

Which shader stage(s) read a graph resource across a contiguous read-run (the passes that read one resource version before the next writer). Carried on a barrier whose Read side spans this run so a backend can satisfy it in a single transition: a write made visible to both a compute consumer and a fragment consumer needs one barrier covering both stages, not a per-consumer read-to-read barrier (which would not carry the producing write). Derived from each reading pass’s PassKind (a render pass samples in the fragment stage, a compute pass in the compute stage); empty on a barrier with no Read side (a write-only producer transition). Add bits as passes read in stages the two current ones do not model.

Implementations

impl ReadStages

pub const fn empty() -> Self

The empty stage set.

pub const fn union(self, other: Self) -> Self

Every stage in either set.

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

Whether every stage in other is set here.

impl ReadStages

pub const FRAGMENT: Self

A render pass’s sampled read (DirectX PIXEL_SHADER_RESOURCE / Vulkan FRAGMENT_SHADER stage).

pub const COMPUTE: Self

A compute pass’s read (DirectX NON_PIXEL_SHADER_RESOURCE / Vulkan COMPUTE_SHADER stage).

pub const fn is_empty(self) -> bool

Whether no stage is set.
