Struct StageIo 

pub struct StageIo {
    pub varyings: HashMap<ShaderLocation, InterfaceVar, BuildHasherDefault<FxHasher>>,
    pub task_payload_size: Option<u32>,
    pub primitive_index: Option<bool>,
}

Fields

varyings: HashMap<ShaderLocation, InterfaceVar, BuildHasherDefault<FxHasher>>

task_payload_size: Option<u32>

This must match between mesh & task shaders

primitive_index: Option<bool>

Fragment shaders cannot input primitive index on mesh shaders that don’t output it on DX12. Therefore, we track between shader stages if primitive index is written (or if vertex shader is used).

This is Some if it was a mesh shader.

Trait Implementations

impl Clone for StageIo

fn clone(&self) -> StageIo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StageIo

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

Formats the value using the given formatter.

impl Default for StageIo

fn default() -> StageIo

Returns the “default value” for a type.
