Enum Alpha 

pub enum Alpha {
    Opaque,
    Transparent,
    Blend,
    HighContrast,
}

Alpha information, part of a Channel.

Variants

Opaque

Indicates a Cell’s foreground or background color is used unchanged.

This is the default.

Transparent

Indicates a Cell’s foreground or background color is derived entirely from the Cells underneath it.

Blend

Indicates a Cell’s foreground or background color will be a composite between its color and the Cells’ corresponding colors.

HighContrast

Indicates the foreground color will be high-contrast, relative to the computed background.

The background cannot be high-contrast.

Implementations

impl Alpha

pub fn display_short(&self) -> &str

Displays the short name identifier of the alpha value.

Trait Implementations

impl Clone for Alpha

fn clone(&self) -> Alpha

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Alpha

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

Formats the value using the given formatter.

impl Default for Alpha

fn default() -> Self

Returns the “default value” for a type.

impl Display for Alpha

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

Formats the value using the given formatter.

impl From<Alpha> for NcAlpha

fn from(alpha: Alpha) -> NcAlpha

Converts to this type from the input type.

impl From<Alpha> for NcAlpha_u32

fn from(align: Alpha) -> NcAlpha_u32

Converts to this type from the input type.

impl From<NcAlpha> for Alpha

fn from(nc: NcAlpha) -> Alpha

Converts to this type from the input type.

impl From<u32> for Alpha

fn from(ncu: NcAlpha_u32) -> Alpha

Converts to this type from the input type.

impl PartialEq for Alpha

fn eq(&self, other: &Alpha) -> 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 Copy for Alpha

impl Eq for Alpha

impl StructuralPartialEq for Alpha
