Enum StencilAction

pub enum StencilAction {
    Keep,
    Zero,
    Replace,
    Incr,
    IncrWrap,
    Decr,
    DecrWrap,
    Invert,
}

An action with the stencil value in the stencil buffer is the stencil test passed.

Variants

Keep

Keeps the current value. This is the default variant.

Zero

Sets the stencil buffer value to 0.

Replace

Sets the stencil buffer value to ref value.

Incr

Increments the current stencil buffer value. Clamps to the maximum representable unsigned value.

IncrWrap

Increments the current stencil buffer value. Wraps stencil buffer value to zero when incrementing the maximum representable unsigned value.

Decr

Decrements the current stencil buffer value. Clamps to 0.

DecrWrap

Decrements the current stencil buffer value. Wraps stencil buffer value to the maximum representable unsigned value when decrementing a stencil buffer value of zero.

Invert

Bitwise inverts the current stencil buffer value.

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for StencilAction

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<StencilAction, <StencilAction as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for StencilAction

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StencilAction

fn eq(&self, other: &StencilAction) -> 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 PartialOrd for StencilAction

fn partial_cmp(&self, other: &StencilAction) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Reflect for StencilAction

where StencilAction: 'static,

fn source_path() -> &'static str

fn type_name(&self) -> &'static str

fn doc(&self) -> &'static str

fn assembly_name(&self) -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.

fn type_assembly_name() -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.
