Trait SymbolDomain

pub trait SymbolDomain {
    type Symbol;
    type Offset: Copy + Debug + Eq + Ord;
}

Expand description

A symbol domain defines both the unit consumed by a pattern and its offset type.

Keeping the offset as an associated type prevents byte-oriented patterns from accidentally being paired with subjects indexed in code units.

Required Associated Types§

One symbol consumed from a subject.

A position in both the pattern source and the subject.

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
