Struct grep_searcher::sinks::Lossy

source ·
pub struct Lossy<F>(pub F)
where
    F: FnMut(u64, &str) -> Result<bool, Error>;
Expand description

A sink that provides line numbers and matches as (lossily converted) strings while ignoring everything else.

This is like UTF8, except that if a match contains invalid UTF-8, then it will be lossily converted to valid UTF-8 by substituting invalid UTF-8 with Unicode replacement characters.

This implementation will return an error on the first match if the searcher was not configured to count lines.

The closure accepts two parameters: a line number and a UTF-8 string containing the matched data. The closure returns a Result<bool, std::io::Error>. If the bool is false, then the search stops immediately. Otherwise, searching continues.

If multi line mode was enabled, the line number refers to the line number of the first line in the match.
