Enum Precision

pub enum Precision {
    Low,
    Medium,
    High,
}

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

High

highp precision

Trait Implementations

impl Clone for Precision

fn clone(&self) -> Precision

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Precision

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

Formats the value using the given formatter.

impl PartialEq for Precision

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Precision

impl StructuralPartialEq for Precision
