Trait kul_core::TextBase

pub trait TextBase where
    Self: Sized, {
    type Pos: SourcePosition;
    fn empty() -> Self;
    fn is_empty(&self) -> bool;
}

The basic interface common across both Texts and TextChunks. This determines the associated type of the characters' positional information; and this provides the ability to construct and check for emptiness.
