Enum Channels 

#[repr(u8)]
pub enum Channels {
    Rgb = 3,
    Rgba = 4,
}

Number of 8-bit channels in a pixel.

Variants

Rgb = 3

Three 8-bit channels (RGB)

Rgba = 4

Four 8-bit channels (RGBA)

Implementations

impl Channels

pub const fn is_rgb(self) -> bool

Returns true if there are 3 channels (RGB).

pub const fn is_rgba(self) -> bool

Returns true if there are 4 channels (RGBA).

pub const fn as_u8(self) -> u8

Converts to an integer (3 if RGB, 4 if RGBA).

Trait Implementations

impl Clone for Channels

fn clone(&self) -> Channels

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Channels

impl Debug for Channels

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

Formats the value using the given formatter.

impl Default for Channels

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Channels

impl From<Channels> for u8

fn from(channels: Channels) -> Self

Converts to this type from the input type.

impl From<Channels> for RawChannels

fn from(value: Channels) -> Self

Converts to this type from the input type.

impl From<RawChannels> for Channels

fn from(value: RawChannels) -> Self

Converts to this type from the input type.

impl Hash for Channels

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 Ord for Channels

fn cmp(&self, other: &Channels) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Channels

fn eq(&self, other: &Channels) -> 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 Channels

fn partial_cmp(&self, other: &Channels) -> 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 StructuralPartialEq for Channels

impl TryFrom<u8> for Channels

type Error = Error

The type returned in the event of a conversion error.

fn try_from(channels: u8) -> Result<Self>

Performs the conversion.
