Struct elipdotter::index::Simple

pub struct Simple { /* private fields */ }

Implementations

impl Simple

pub fn new( proximity_threshold: f32, proximity_algorithm: Algorithm, word_count_limit: usize ) -> Self

proximity_threshold is the threshold where alike words are also accepted. It uses the range [0..1], where values nearer 0 allow more words. The default is 0.9.

proximity_threshold is the algorithm used for proximity checking of words.

word_count_limit is the number of words in this index where only words with the first character is used for approximate matching. Default is 2_500.

pub fn ingest(&mut self, other: Self)

Merges other with self.

Trait Implementations

impl Debug for Simple

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Simple

Self::new with proximity_threshold set to 0.85.

fn default() -> Self

Returns the “default value” for a type.

impl<'a> Provider<'a> for Simple

fn insert_word(&mut self, word: impl AsRef<str>, document: Id, _index: usize)

O(log n log n)

fn remove_document(&mut self, document: Id)

O(n log n)

fn contains_word(&self, word: impl AsRef<str>, document: Id) -> bool

O(log n log n)

fn documents_with_word( &'a self, word: impl AsRef<str> ) -> Option<Self::DocumentIter>

O(log n)

Iterator is O(1) - running this and consuming the iterator is O(n log n).

You can get the length of the list using the ExactSizeIterator trait.

type DocumentIter = Copied<Iter<'a, Id>>

type WordIter = Keys<'a, Arc<Alphanumeral<StrPtr>>, SimpleDocMap>

type WordFilteredIter = Map<Range<'a, Arc<Alphanumeral<StrPtr>>, SimpleDocMap>, fn(_: (&'a Arc<Alphanumeral<StrPtr>>, &'a SimpleDocMap)) -> &'a Arc<Alphanumeral<StrPtr>>>

fn size(&self) -> usize

Estimate of the number of bytes this index uses in memory, specifically the heap.

fn word_count_upper_limit(&self) -> usize

fn word_count_limit(&self) -> usize

The limit of Self::word_count_upper_limit where Self::words_starting_with is used instead of Self::words.

fn words(&'a self) -> Self::WordIter

fn words_starting_with(&'a self, c: char) -> Self::WordFilteredIter

fn word_proximity_threshold(&self) -> f32

fn word_proximity_algorithm(&self) -> Algorithm

fn digest_document(&mut self, id: Id, content: &str)

Only adds words which are alphanumeric.
