[−][src]Struct grep_printer::JSONSink
An implementation of Sink
associated with a matcher and an optional file
path for the JSON printer.
This type is generic over a few type parameters:
'p
refers to the lifetime of the file path, if one is provided. When no file path is given, then this is'static
.'s
refers to the lifetime of theJSON
printer that this type borrows.M
refers to the type of matcher used bygrep_searcher::Searcher
that is reporting results to this sink.W
refers to the underlying writer that this printer is writing its output to.
Methods
impl<'p, 's, M: Matcher, W: Write> JSONSink<'p, 's, M, W>
[src]
pub fn has_match(&self) -> bool
[src]
Returns true if and only if this printer received a match in the previous search.
This is unaffected by the result of searches before the previous search.
pub fn match_count(&self) -> u64
[src]
Return the total number of matches reported to this sink.
This corresponds to the number of times Sink::matched
is called.
pub fn binary_byte_offset(&self) -> Option<u64>
[src]
If binary data was found in the previous search, this returns the offset at which the binary data was first detected.
The offset returned is an absolute offset relative to the entire set of bytes searched.
This is unaffected by the result of searches before the previous
search. e.g., If the search prior to the previous search found binary
data but the previous search found no binary data, then this will
return None
.
pub fn stats(&self) -> &Stats
[src]
Return a reference to the stats produced by the printer for all searches executed on this sink.

) -> Result<bool, Self::Error>
[src]
&mut self,
_searcher: &Searcher
) -> Result<bool, Self::Error>
This method is called whenever a break in contextual lines is found, and is optional to implement. By default, it does nothing and returns true
. Read more
default fn binary_data(
&mut self,
_searcher: &Searcher,
_binary_byte_offset: u64
) -> Result<bool, Self::Error>
[src]
&mut self,
_searcher: &Searcher,
_binary_byte_offset: u64
) -> Result<bool, Self::Error>
This method is called whenever binary detection is enabled and binary data is found. If binary data is found, then this is called at least once for the first occurrence with the absolute byte offset at which the binary data begins. Read more
