    Never,
    Less,
    Equal,
    LessEqual,
    Greater,

}

Comparison function used for depth and stencil operations.

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

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

GreaterEqual

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

Always

Function always passes

Implementations

impl CompareFunction

pub fn needs_ref_value(self) -> bool

Returns true if the comparison depends on the reference value.

Trait Implementations

impl Clone for CompareFunction

pub fn clone(&self) -> CompareFunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompareFunction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CompareFunction

pub fn deserialize<__D>(
    __deserializer: __D
) -> Result<CompareFunction, <__D as Deserializer<'de>>::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Hash for CompareFunction

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl PartialEq<CompareFunction> for CompareFunction

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