Enum CompareFunction 

pub enum CompareFunction {
    Less,
    LessEqual,
    Greater,
    GreaterEqual,
    Equal,
    NotEqual,
    Always,
    Never,
}

Optional depth-compare function for shadow/depth sampling.

Variants

Less

Passes when the sampled value is less than the reference.

LessEqual

Passes when the sampled value is less than or equal to the reference.

Greater

Passes when the sampled value is greater than the reference.

GreaterEqual

Passes when the sampled value is greater than or equal to the reference.

Equal

Passes when the sampled value equals the reference.

NotEqual

Passes when the sampled value differs from the reference.

Always

Always passes.

Never

Never passes.

Trait Implementations

impl Clone for CompareFunction

fn clone(&self) -> CompareFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CompareFunction

impl Debug for CompareFunction

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

Formats the value using the given formatter.

impl Eq for CompareFunction

impl Hash for CompareFunction

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CompareFunction

fn eq(&self, other: &CompareFunction) -> 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.
