Struct ResourceHandles 

pub struct ResourceHandles { /* private fields */ }

Per-kind handles assigned to each resource, keyed by its identity.

Implementations

impl ResourceHandles

pub fn assign(&mut self, kind: ResourceKind, id: AssetId) -> u32

Give one resource the next handle in its kind’s space and record it. Declaration order in, dense 0..N out.

pub fn get(&self, kind: ResourceKind, id: AssetId) -> Option<u32>

The handle a resource received, if it was assigned one.

pub fn count(&self, kind: ResourceKind) -> u32

How many handles a kind has assigned: its table length.

pub fn from_assets( assets: impl IntoIterator<Item = (AssetId, ResourceKind)>, ) -> Self

Assign handles across a world’s resources, in the order given. The caller has already classified each asset and passes only the resources; each kind counts independently from zero.

pub fn assign_mesh_sources( &mut self, sources: impl IntoIterator<Item = (AssetId, MeshBlock)>, )

Assign the shared mesh-source handle space over a world’s geometry producers, given in declaration order with the block each belongs to. Handles go out in block order, declaration order within a block.

pub fn assign_shader(&mut self, id: AssetId) -> u32

Give one Shader the next handle in the shader space and record it.

pub fn shader(&self, id: AssetId) -> Option<u32>

The handle a Shader received, if it was assigned one.

pub fn shader_count(&self) -> u32

How many shader handles were assigned.
