The data to search.

Methods

impl<'a> Search<'a>

fn new(data: &'a [(Range, MetaData)]) -> Search<'a>

Creates a new search.

fn for_string<T, F>(&'a self, name: &str, val: &str, f: F) -> Result<T, (Range, ParseError)> where F: FnOnce(Search<'a>) -> Result<T, (Range, ParseError)>

Searches anywhere in meta data for a string. Calls closure on the first match.

fn f64(&mut self, name: &str) -> Result<f64, (Range, ParseError)>
