Trait Decoder

pub trait Decoder<T, C>
where
    T: Copy + Clone + FromPrimitive + Num + NumAssignOps + NumCast + PartialOrd + Display + PixelBound,
    C: ColourModel,
{
    // Required method
    fn decode(&self, bytes: &[u8]) -> Result<Image<T, C>>;

    // Provided method
    fn decode_file<P: AsRef<Path>>(&self, filename: P) -> Result<Image<T, C>> { ... }
}

Trait for an image decoder, use this to get an image from a byte stream

Required Methods

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

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

Provided Methods

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

Given a filename decode an image performing any necessary conversions.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

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.
