Struct ResourcePool 

pub struct ResourcePool {
    pub max_idle_frames: u64,
    /* private fields */
}

Manages physical resources with frame-based lifetime tracking. Reuses allocations between frames when descriptors match.

Fields

max_idle_frames: u64

Maximum number of frames a resource can be unused before being freed.

Implementations

impl ResourcePool

pub fn new() -> Self

pub fn begin_frame(&mut self)

Advance to the next frame. Frees resources that have been idle too long.

pub fn end_frame(&self) -> PoolFrameStats

End the current frame. Reports statistics.

pub fn acquire( &mut self, descriptor: ResourceDescriptor, lifetime: ResourceLifetime, bb_w: u32, bb_h: u32, ) -> ResourceHandle

Acquire a resource matching the given descriptor. Reuses a free slot if possible.

pub fn release(&mut self, handle: ResourceHandle)

Release a resource back to the free list.

pub fn record_write( &mut self, handle: ResourceHandle, pass_idx: usize, pass_name: &str, )

Mark a pass as writing to a resource.

pub fn record_read( &mut self, handle: ResourceHandle, pass_idx: usize, _pass_name: &str, )

Mark a pass as reading from a resource.

pub fn descriptor(&self, handle: ResourceHandle) -> Option<&ResourceDescriptor>

Get the descriptor for a handle.

pub fn physical(&self, handle: ResourceHandle) -> Option<&PhysicalResource>

Get a physical resource by handle.

pub fn compute_aliasing(&mut self, total_passes: usize) -> &[Vec<usize>]

Compute aliasing groups: resources whose lifetimes don’t overlap can share memory.

pub fn detect_raw_hazards(&self) -> Vec<(String, u32)>

Check all version chains for read-after-write hazards.

pub fn estimate_memory_budget(&self, bb_w: u32, bb_h: u32) -> MemoryBudget

Estimate total memory budget for all active resources.

pub fn total_slots(&self) -> usize

Total number of resources (including free slots).

pub fn active_count(&self) -> usize

Number of active (non-free) resources.

pub fn version_chain( &self, handle: ResourceHandle, ) -> Option<&ResourceVersionChain>

Get the version chain for a resource handle.

Trait Implementations

impl Default for ResourcePool

fn default() -> Self

Returns the “default value” for a type.
