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 ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
