Struct Edit 

pub struct Edit {
    pub start: usize,
    pub old_end: usize,
    pub new_end: usize,
}

One replacement in a field’s text, in bytes: start..old_end of the text before became start..new_end of the text after. The fields are tree-sitter’s InputEdit byte fields.

Fields

start: usize

old_end: usize

new_end: usize

Implementations

impl Edit

pub fn between(before: &str, after: &str) -> Self

The smallest edit that turns before into after: what they share at either end is left out.

pub fn map(self, range: Range<usize>) -> Option<Range<usize>>

Where range of the text before lands in the text after. A range wholly before the edit stays, one wholly after moves by the length the edit added or took, one the edit falls inside grows or shrinks with it, and one the edit cuts keeps the part it did not touch. None when the edit took all of it.
