Implementations

impl PnmSubtype

pub fn magic_constant(self) -> &'static [u8; 2]

Get the two magic constant bytes corresponding to this format subtype.

pub fn sample_encoding(self) -> SampleEncoding

Whether samples are stored as binary or as decimal ascii

Trait Implementations

impl Clone for PnmSubtype

fn clone(&self) -> PnmSubtype

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PnmSubtype

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

Formats the value using the given formatter.

impl PartialEq for PnmSubtype

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