Struct Interface 

pub struct Interface {
    pub stage: Stage,
    pub inputs: Vec<Varying>,
    pub outputs: Vec<Varying>,
    pub resources: Vec<Resource>,
    pub facts: StageFacts,
}

What a program exposes: its stage, the varyings it takes and gives, and the resources it binds.

Fields

stage: Stage

The stage the program runs in.

inputs: Vec<Varying>

The varyings the program reads, one per label.

outputs: Vec<Varying>

The varyings the program writes, one per label.

resources: Vec<Resource>

The resources the program binds, each with a different id.

facts: StageFacts

Facts the stage adds; Interface::verify checks that they fit the stage.

Implementations

impl Interface

pub fn resource(&self, id: ResourceId) -> Option<&Resource>

The resource with this id.

pub fn verify(&self) -> Result<(), String>

The interface’s own invariants: one varying per label in each direction, values of 1 to 4 lanes, a colour output Target(n) of a pixel stage with n of 0 to 7 and no such input, resource ids unique, every resource spanning at least one binding with a buffer stride (a multiple of 4, up to 2048) or element width that means something, every constant of a buffer (or of a tbuffer view’s layout) inside it with a layout that does not overflow, a hidden counter that belongs to a storage resource and has no binding of its own, a D3D register class that fits the resource’s kind, and no two resources on one register of one class and space.

Trait Implementations
