Struct tantivy::fastfield::U64FastFieldReader

pub struct U64FastFieldReader { /* fields omitted */ }

FastFieldReader for unsigned 64-bits integers.

Methods

impl U64FastFieldReader

pub fn min_value(&self) -> u64

Returns the minimum value for this fast field.

The min value does not take in account of possible deleted document, and should be considered as a lower bound of the actual minimum value.

pub fn max_value(&self) -> u64

Returns the maximum value for this fast field.

The max value does not take in account of possible deleted document, and should be considered as an upper bound of the actual maximum value.

Trait Implementations

impl Clone for U64FastFieldReader

fn clone(&self) -> U64FastFieldReader

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl FastFieldReader for U64FastFieldReader

type ValueType = u64

Type of the value stored in the fastfield.

fn get(&self, doc: DocId) -> u64

Return the value associated to the given document.

fn is_enabled(field_type: &FieldType) -> bool

Returns true iff the given field_type makes it possible to access the field values via a fastfield.

fn get_range(&self, start: u32, output: &mut [Self::ValueType])

Fills an output buffer with the fast field values associated with the DocId going from start to start + output.len().

fn open(data: ReadOnlySource) -> U64FastFieldReader

Opens a new fast field reader given a read only source.

Panics

Panics if the data is corrupted.

impl From<Vec<u64>> for U64FastFieldReader

fn from(vals: Vec<u64>) -> U64FastFieldReader

Performs the conversion.
