Enum JpegMode 

#[non_exhaustive]
pub enum JpegMode {
    Baseline,
    Extended,
    Progressive,
    Lossless,
}

JPEG encoding mode.

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.

Baseline

Baseline sequential DCT (most compatible)

Extended

Extended sequential DCT (12-bit precision)

Progressive

Progressive DCT (multiple scans)

Lossless

Lossless (not implemented)

Trait Implementations

impl Clone for JpegMode

fn clone(&self) -> JpegMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JpegMode

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

Formats the value using the given formatter.

impl Default for JpegMode

fn default() -> JpegMode

Returns the “default value” for a type.

impl Hash for JpegMode

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 PartialEq for JpegMode

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