Struct grep_searcher::sinks::Lossy [−][src]
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, 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.
