Enum ImageFormat

#[non_exhaustive]
#[repr(u8)]
pub enum ImageFormat {
    Rgba8 = 0,
}

Defines the pixel format of an image.

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.

Rgba8 = 0

32-bit RGBA with 8-bit channels.

Implementations

impl ImageFormat

pub fn size_in_bytes(self, width: u32, height: u32) -> Option<usize>

Returns the required size in bytes for an image in this format of the given dimensions.

A result of None indicates an overflow in the size calculation.

Trait Implementations

impl CheckedBitPattern for ImageFormat

type Bits = u8

Self must have the same layout as the specified Bits except for the possible invalid bit patterns being checked during is_valid_bit_pattern.

fn is_valid_bit_pattern(bits: &u8) -> bool

If this function returns true, then it must be valid to reinterpret bits as &Self.

impl Clone for ImageFormat

fn clone(&self) -> ImageFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Contiguous for ImageFormat

const MIN_VALUE: u8 = 0u8

The lower inclusive bound for valid instances of this type.

const MAX_VALUE: u8 = 0u8

The upper inclusive bound for valid instances of this type.

type Int = u8

The primitive integer type with an identical representation to this type.

fn from_integer(value: Self::Int) -> Option<Self>

If value is within the range for valid instances of this type, returns Some(converted_value), otherwise, returns None.

fn into_integer(self) -> Self::Int

Perform the conversion from C into the underlying integral type. This mostly exists otherwise generic code would need unsafe for the value as integer

impl Debug for ImageFormat

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

Formats the value using the given formatter.

impl PartialEq for ImageFormat

fn eq(&self, other: &ImageFormat) -> 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 Zeroable for ImageFormat

fn zeroed() -> Self

Calls zeroed.

impl Copy for ImageFormat

impl Eq for ImageFormat

impl NoUninit for ImageFormat

impl StructuralPartialEq for ImageFormat
