Struct PpmDecoder

pub struct PpmDecoder;

Decoder type for a PPM image.

Trait Implementations

impl Clone for PpmDecoder

fn clone(&self) -> PpmDecoder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PpmDecoder

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

Formats the value using the given formatter.

impl<T> Decoder<T, RGB> for PpmDecoder

where T: Copy + Clone + Num + NumAssignOps + NumCast + PartialOrd + Display + PixelBound + FromPrimitive,

Implements the decoder trait for the PpmDecoder.

The ColourModel type argument is locked to RGB - this prevents calling RGB::into::() unnecessarily which is unavoidable until trait specialisation is stabilised.

fn decode(&self, bytes: &[u8]) -> Result<Image<T, RGB>>

From the bytes decode an image, will perform any scaling or conversions required to represent elements with type T.

fn decode_file<P: AsRef<Path>>(&self, filename: P) -> Result<Image<T, C>>

Given a filename decode an image performing any necessary conversions.

impl Default for PpmDecoder

fn default() -> PpmDecoder

Returns the “default value” for a type.

impl Hash for PpmDecoder

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 PpmDecoder

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