Struct tantivy::termdict::TermMerger
source · [−]pub struct TermMerger<'a> { /* private fields */ }Expand description
Given a list of sorted term streams, returns an iterator over sorted unique terms.
The item yielded is actually a pair with
- the term
- a slice with the ordinal of the segments containing the term.
Implementations
sourceimpl<'a> TermMerger<'a>
impl<'a> TermMerger<'a>
sourcepub fn new(streams: Vec<TermStreamer<'a>>) -> TermMerger<'a>
pub fn new(streams: Vec<TermStreamer<'a>>) -> TermMerger<'a>
Stream of merged term dictionary
sourcepub fn matching_segments<'b: 'a>(
&'b self
) -> impl 'b + Iterator<Item = (usize, TermOrdinal)>
pub fn matching_segments<'b: 'a>(
&'b self
) -> impl 'b + Iterator<Item = (usize, TermOrdinal)>
Iterator over (segment ordinal, TermOrdinal) sorted by segment ordinal
This method may be called
if Self::advance has been called before
and true was returned.
sourcepub fn advance(&mut self) -> bool
pub fn advance(&mut self) -> bool
Advance the term iterator to the next term.
Returns true if there is indeed another term
false if there is none.
sourcepub fn key(&self) -> &[u8]ⓘNotable traits for &'_ [u8]impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]
pub fn key(&self) -> &[u8]ⓘNotable traits for &'_ [u8]impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]
Returns the current term.
This method may be called
if Self::advance has been called before
and true was returned.
sourcepub fn current_segment_ords_and_term_infos<'b: 'a>(
&'b self
) -> impl 'b + Iterator<Item = (usize, TermInfo)>
pub fn current_segment_ords_and_term_infos<'b: 'a>(
&'b self
) -> impl 'b + Iterator<Item = (usize, TermInfo)>
Iterator over (segment ordinal, TermInfo) pairs iterator sorted by the ordinal.
This method may be called
if Self::advance has been called before
and true was returned.
