}

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

Clear

Returns 0.

And

Returns source & destination.

AndReverse

Returns source & !destination.

Copy

Returns source.

AndInverted

Returns !source & destination.

Noop

Returns destination.

Xor

Returns source ^ destination.

Or

Returns source | destination.

Nor

Returns !(source | destination).

Equivalent

Returns !(source ^ destination).

Invert

Returns !destination.

OrReverse

Returns `source | !destination.

CopyInverted

Returns !source.

OrInverted

Returns !source | destination.

Nand

Returns !(source & destination).

Set

Returns !0 (all bits set to 1).

Trait Implementations

impl Default for LogicOp

fn default() -> LogicOp

Returns the "default value" for a type.

impl PartialEq<LogicOp> for LogicOp

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

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

#[must_use]

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

This method tests for !=.

impl Copy for LogicOp

impl Eq for LogicOp

impl Debug for LogicOp

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

Formats the value using the given formatter.

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.
