Enum naga::front::glsl::Precision

source ·
pub enum Precision {
    Low,
    Medium,
    High,
}
Expand description

A precision hint used in GLSL declarations.

Precision hints can be used to either speed up shader execution or control the precision of arithmetic operations.

To use a precision hint simply add it before the type in the declaration.

mediump float a;

The default when no precision is declared is highp which means that all operations operate with the type defined width.

For mediump and lowp operations follow the spir-v RelaxedPrecision decoration semantics.

Variants§

§

Low

lowp precision

Medium

mediump precision

impl PartialEq for Precision

source§

fn eq(&self, other: &Precision) -> bool
