[−][src]Struct grep_searcher::sinks::UTF8
A sink that provides line numbers and matches as strings while ignoring everything else.
This implementation will return an error if a match contains invalid
UTF-8 or if the searcher was not configured to count lines. Errors
on invalid UTF-8 can be suppressed by using the Lossy
sink instead
of this one.
The closure accepts two parameters: a line number and a UTF-8 string
containing the matched data. The closure returns a
Result<bool, 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.

fn begin(&mut self, _searcher: &Searcher) -> Result<bool, Self::Error>
[src]
This method is called when a search has begun, before any search is executed. By default, this does nothing. Read more
