Struct Edit 

pub struct Edit {
    pub range: Range<usize>,
    pub insert: String,
}

A single contiguous text edit: replace range (a byte range in the old text) with insert.

Fields

range: Range<usize>

insert: String

Implementations

impl Edit

pub fn delta(&self) -> isize

The signed length change this edit applies to text after range.

Diagnostic offsets at or after the edit shift by exactly this much, which is what lets a tier keep the errors it did not regenerate.

pub fn fits(&self, text: &str) -> bool

Whether this edit fits text: in bounds, non-inverted, and both offsets on char boundaries. Check before slicing — the edit is untrusted.

pub fn apply(&self, old: &str) -> String

Apply the edit to old, producing the new text.

Panics

If the edit does not fit old.
