}

Which logical operation to apply to the output values.

The operation is applied individually for each channel (red, green, blue and alpha).

Only relevant for integer or unsigned attachments.

Also note that some implementations don’t support logic operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Clear = 0

Returns 0.

And = 1

Returns source & destination.

AndReverse = 2

Returns source & !destination.

Copy = 3

Returns source.

AndInverted = 4

Returns !source & destination.

Noop = 5

Returns destination.

Xor = 6

Returns source ^ destination.

Or = 7

Returns source | destination.

Nor = 8

Returns !(source | destination).

Equivalent = 9

Returns !(source ^ destination).

Invert = 10

Returns !destination.

OrReverse = 11

Returns `source | !destination.

CopyInverted = 12

Returns !source.

OrInverted = 13

Returns !source | destination.

Nand = 14

Returns !(source & destination).

Set = 15

Returns !0 (all bits set to 1).

Trait Implementations

impl Clone for LogicOp

fn clone(&self) -> LogicOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LogicOp

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

Formats the value using the given formatter.

impl Default for LogicOp

fn default() -> LogicOp

Returns the “default value” for a type.

impl From<LogicOp> for LogicOp

fn from(val: LogicOp) -> Self

Converts to this type from the input type.

impl Hash for LogicOp

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 LogicOp

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<LogicOp> for LogicOp

type Error = ()

The type returned in the event of a conversion error.

fn try_from(val: LogicOp) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for LogicOp

impl Eq for LogicOp

impl StructuralEq for LogicOp

impl StructuralPartialEq for LogicOp
