Implementations

impl SOFMarkers

pub fn is_sequential_dct(self) -> bool

Check if a certain marker is sequential DCT or not

pub fn is_lossless(self) -> bool

Check if a marker is a Lossles type or not

pub fn is_progressive(self) -> bool

Check whether a marker is a progressive marker or not

pub fn from_int(int: u16) -> Option<SOFMarkers>

Create a marker from an integer

Trait Implementations

impl Clone for SOFMarkers

fn clone(&self) -> SOFMarkers

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SOFMarkers

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

Formats the value using the given formatter.

impl Default for SOFMarkers

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SOFMarkers

fn eq(&self, other: &SOFMarkers) -> 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 Copy for SOFMarkers

impl Eq for SOFMarkers

impl StructuralPartialEq for SOFMarkers
