Struct HotReloadTracker 

pub struct HotReloadTracker { /* private fields */ }

Tracks shader source modification times to support hot reload.

In production this would watch file system events; here timestamps are set manually for testing.

Implementations

impl HotReloadTracker

pub fn new() -> Self

Create a new tracker.

pub fn touch(&mut self, name: impl Into<String>, time: u64)

Record a modification for name at the given logical time.

pub fn record_compile(&mut self, name: impl Into<String>, time: u64)

Record that name was compiled at the given logical time.

pub fn needs_recompile(&self, name: &str) -> bool

Returns true when name has been modified since it was last compiled.

pub fn stale_shaders(&self) -> Vec<&str>

Return all shader names that need recompilation.

impl HotReloadTracker

pub fn touch_batch(&mut self, names: &[&str], time: u64)

Touch multiple shaders at once with the same logical timestamp.

pub fn flush_stale(&mut self, time: u64)

Record that all currently stale shaders have been recompiled at time.

pub fn never_compiled(&self) -> Vec<&str>

Return the set of shader names that have been modified but never compiled.
