source§fn find(&self, haystack: &[u8], span: Span) -> Option<Span>
fn find(&self, haystack: &[u8], span: Span) -> Option<Span>
Run this prefilter on
haystack[span.start..end]
and return a matching
span if one exists. Read moresource§fn prefix(&self, haystack: &[u8], span: Span) -> Option<Span>
fn prefix(&self, haystack: &[u8], span: Span) -> Option<Span>
Returns the span of a prefix of
haystack[span.start..span.end]
if
the prefilter matches. Read moresource§fn memory_usage(&self) -> usize
fn memory_usage(&self) -> usize
Returns the heap memory, in bytes, used by the underlying prefilter.
source§fn is_fast(&self) -> bool
fn is_fast(&self) -> bool
Implementations might return true here if they believe themselves to
be “fast.” See
Prefilter::is_fast
