Struct ResourceVersionChain 

pub struct ResourceVersionChain {
    pub handle: ResourceHandle,
    pub descriptor: ResourceDescriptor,
    pub lifetime: ResourceLifetime,
    pub versions: Vec<(u32, String)>,
    pub readers: HashMap<u32, Vec<String>>,
}

Tracks all versions of a single logical resource within one frame, enabling read-after-write hazard detection.

Fields

handle: ResourceHandle

descriptor: ResourceDescriptor

lifetime: ResourceLifetime

versions: Vec<(u32, String)>

Ordered list of (version, writer_pass_name).

readers: HashMap<u32, Vec<String>>

Readers per version: version -> list of pass names.

Implementations

impl ResourceVersionChain

pub fn new( handle: ResourceHandle, descriptor: ResourceDescriptor, lifetime: ResourceLifetime, ) -> Self

pub fn record_write(&mut self, pass_name: &str) -> u32

Record a write, bumping version.

pub fn record_read(&mut self, version: u32, pass_name: &str)

Record a read at a specific version.

pub fn current_version(&self) -> u32

The current (latest) version.

pub fn has_raw_hazard(&self) -> bool

Detect if a read-after-write hazard exists: a pass reads version N while another pass writes version N+1.
