Trait loe::Transform

pub trait Transform {
    fn transform_buffer(
        &mut self, 
        in_ptr: usize, 
        out_ptr: usize, 
        input: &[u8], 
        output: &mut [u8]
    ) -> usize;
}

Trait used for transformation of the input. It works on buffers due to the memory consumption and performance reasons.

Required Methods

fn transform_buffer(
    &mut self,
    in_ptr: usize,
    out_ptr: usize,
    input: &[u8],
    output: &mut [u8]
) -> usize

Transforms the input to the output. Most of the time it just copies the byte at index in_ptr from the input to the index out_ptr of the output. The function also returns the position of the first next writable byte in the output buffer, that is, one behind the last written one.

Trait Implementations

impl From<TransformMode> for Box<dyn Transform>

fn from(val: TransformMode) -> Self

Converts to this type from the input type.
