Struct FrameGraph 

pub struct FrameGraph { /* private fields */ }

A full-frame resource graph with transient resource aliasing.

Implementations

impl FrameGraph

pub fn new() -> Self

Create an empty frame graph.

pub fn add_pass(&mut self, pass: FramePass)

Add a render pass.

pub fn declare_resource(&mut self, name: impl Into<String>, size: usize)

Declare a transient resource with its size.

pub fn alias_resources(&mut self)

Run a simple aliasing pass: resources that do not overlap in lifetime share the same memory offset.

pub fn peak_memory(&self) -> usize

Compute the peak memory required (maximum end of any allocation).

pub fn pass_count(&self) -> usize

Number of passes.

pub fn barriers_for_pass(&self, idx: usize) -> &[PipelineBarrier]

Get all barriers for a given pass by index.

pub fn all_barriers(&self) -> Vec<&PipelineBarrier>

Collect all pipeline barriers across the frame in order.

pub fn resources_for_pass(&self, idx: usize) -> Vec<&str>

Find all resources used by pass at index idx.

Trait Implementations

impl Debug for FrameGraph

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FrameGraph

fn default() -> FrameGraph

Returns the “default value” for a type.
