Trait CoordMapper

pub trait CoordMapper {
    type Output;

    // Required method
    fn map<CT>(
        coord_trans: &CT,
        from: &<CT as CoordTranslate>::From,
        rect: &Rect,
    ) -> Self::Output
       where CT: CoordTranslate;
}

Useful to translate from guest coordinates to backend coordinates

Required Associated Types

type Output

Specifies the output data from the translation

Required Methods

fn map<CT>( coord_trans: &CT, from: &<CT as CoordTranslate>::From, rect: &Rect, ) -> Self::Output

where CT: CoordTranslate,

Performs the translation from guest coordinates to backend coordinates

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 CoordMapper for BackendCoordAndZ

type Output = ((i32, i32), i32)

impl CoordMapper for BackendCoordOnly

type Output = (i32, i32)
