Enum SurfaceChannels

pub enum SurfaceChannels {
    RGB,
    RGBA,
    L,
    LA,
    D,
    XYZ,
    XYZW,
}

The per-texel layout of the format. The length of the enumeration string indicates how many channels there are and each letter represents the name of a channel. There are typically 1 to 4 channels.

Variants

RGB

Red/Green/Blue color map.

RGBA

Red/Green/Blue/Alpha map, often used for color and transparency or other things packed into channel A, such as specular power.

L

Luminance map, often used for light mapping.

LA

Luminance/Alpha map, often used for light mapping.

D

Depth map, often used for displacement, parallax, relief, or shadow mapping.

XYZ

Typically used for normal maps or three-component displacement maps.

XYZW

Typically used for normal maps, where W is the depth for relief or parallax mapping.

Implementations

impl SurfaceChannels

pub fn to_str(self) -> &'static str

The XML name of a value in this enumeration.

Trait Implementations

impl Clone for SurfaceChannels

fn clone(&self) -> SurfaceChannels

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SurfaceChannels

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

Formats the value using the given formatter.

impl Display for SurfaceChannels

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

Formats the value using the given formatter.

impl FromStr for SurfaceChannels

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl PartialEq for SurfaceChannels

fn eq(&self, other: &SurfaceChannels) -> 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.
