Enum ImageQuality 

#[repr(u8)]
pub enum ImageQuality {
    Low = 0,
    Medium = 1,
    High = 2,
}

Defines the desired quality for sampling an image.

Variants

Low = 0

Lowest quality with best performance characteristics.

This is typically nearest neighbor sampling.

Medium = 1

Medium quality with reasonable performance characteristics.

This is typically bilinear sampling.

High = 2

Highest quality with worst performance characteristics.

This is typically bicubic sampling.

Trait Implementations

impl CheckedBitPattern for ImageQuality

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 ImageQuality

fn clone(&self) -> ImageQuality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Contiguous for ImageQuality

const MIN_VALUE: u8

The lower inclusive bound for valid instances of this type.

const MAX_VALUE: u8

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 ImageQuality

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

Formats the value using the given formatter.

impl Default for ImageQuality

fn default() -> ImageQuality

Returns the “default value” for a type.

impl PartialEq for ImageQuality

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

fn zeroed() -> Self

Calls zeroed.

impl Copy for ImageQuality

impl Eq for ImageQuality

impl NoUninit for ImageQuality

impl StructuralPartialEq for ImageQuality
