Struct PatternMatch 

pub struct PatternMatch {
    pub byte_start: usize,
    pub byte_end: usize,
    pub text: String,
    pub captures: HashMap<String, String>,
}

A match from an ast-grep pattern with captured metavariables.

Fields

byte_start: usize

Byte range of the entire match

byte_end: usize

text: String

The matched text

captures: HashMap<String, String>

Captured metavariables: name -> text Note: For byte spans of captures, use find_capture_span()

Implementations

impl PatternMatch

pub fn find_capture_span(&self, name: &str) -> Option<(usize, usize)>

Find the byte span of a capture within the matched text.

This is an approximation that finds the first occurrence of the captured text within the matched region.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PatternMatch

fn fmt(&self, f: &mut Formatter<'_>) -> Result
