Expand description

Comparison function used for depth and stencil operations.

Corresponds to WebGPU GPUCompareFunction.

Variants§

§

Never

Function never passes

§

Less

Function passes if new value less than existing value

§

Equal

Function passes if new value is equal to existing value. When using this compare function, make sure to mark your Vertex Shader’s @builtin(position) output as @invariant to prevent artifacting.

§

LessEqual

Function passes if new value is less than or equal to existing value

§

Greater

Function passes if new value is greater than existing value

§

NotEqual

Function passes if new value is not equal to existing value. When using this compare function, make sure to mark your Vertex Shader’s @builtin(position) output as @invariant to prevent artifacting.

§

GreaterEqual

Function passes if new value is greater than or equal to existing value

§

Always

Function always passes

Implementations§

Returns true if the comparison depends on the reference value.

Trait Implementations§

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
Feeds this value into the given Hasher. Read more
Feeds a slice of this type into the given Hasher. Read more
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
