Struct kas_text::Range

pub struct Range {
    pub start: u32,
    pub end: u32,
}

Range type

Essentially this is just a std::ops::Range<u32>, but with convenient implementations.

Note that we consider u32 large enough for any text we wish to display and the library is too complex to be useful on 16-bit CPUs, so using u32 makes more sense than usize.

Fields

start: u32

end: u32
