Implementations

source

impl<V: Pod, I: Pod, TM: Pod, FM: Pod> BufferPool<Queue, Buffer, V, I, TM, FM>

source

pub fn from_device(device: &Device) -> Self

source

impl<Q: Queue, B, V: Pod, I: Pod, TM: Pod, FM: Pod> BufferPool<Q, B, V, I, TM, FM>

source

pub fn new(
 vertices: BackingBufferDescriptor,
 indices: BackingBufferDescriptor,
 layer_metadata: BackingBufferDescriptor,
 feature_metadata: BackingBufferDescriptor
) -> Self

source

fn align(
    stride: BufferAddress,
    elements: BufferAddress,
    usable_elements: BufferAddress
) -> (BufferAddress, BufferAddress)

The VertexBuffers can contain padding elements. Not everything from a VertexBuffers is useable. The function returns the bytes and aligned_bytes. See OverAlignedVertexBuffer.

source

pub fn get_loaded_layers_at(
&self,
coords: &WorldTileCoords
) -> Option<HashSet<&str>>

source

pub fn allocate_layer_geometry(
 &mut self,
 queue: &Q,
 coords: WorldTileCoords,
 style_layer: StyleLayer,
 geometry: &OverAlignedVertexBuffer<V, I>,
 layer_metadata: TM,
 feature_metadata: &[FM]
)

Allocates

geometry
layer_metadata and
feature_metadata for a layer. This function is able to dynamically evict layers if there is not enough space available.

    &self,
    queue: &Q,
    entry: &IndexEntry,
    layer_metadata: TM
