Struct GpuResourceManager 

pub struct GpuResourceManager { /* private fields */ }

Simple GPU resource manager that tracks allocations and their sizes.

Implementations

impl GpuResourceManager

pub fn new() -> Self

Create a new, empty resource manager.

pub fn allocate( &mut self, resource_type: ResourceType, size_bytes: usize, label: impl Into<String>, ) -> Result<ResourceHandle, String>

Allocate a new resource.

Returns a valid ResourceHandle on success, or an error string if size_bytes is zero.

pub fn free(&mut self, handle: ResourceHandle) -> bool

Free a previously allocated resource.

Returns true if the resource existed and was freed, false otherwise.

pub fn total_gpu_bytes(&self) -> usize

Total bytes currently allocated in GPU memory (device-local resources).

pub fn total_bytes(&self) -> usize

Total bytes across all resource types.

pub fn allocation_count(&self) -> usize

Number of live allocations.

pub fn resource_type(&self, handle: ResourceHandle) -> Option<ResourceType>

Query the type of a resource by handle.

pub fn resource_size(&self, handle: ResourceHandle) -> Option<usize>

Query the size of a resource in bytes.

pub fn resource_label(&self, handle: ResourceHandle) -> Option<&str>

Query the label of a resource.

pub fn is_alive(&self, handle: ResourceHandle) -> bool

Returns true if the handle refers to a live allocation.

Trait Implementations

impl Default for GpuResourceManager

fn default() -> Self

Returns the “default value” for a type.
