source · [−]

pub struct MultiValuedFastFieldReader<Item: FastValue> { /* private fields */ }

Expand description

Reader for a multivalued u64 fast field.

The reader is implemented as two u64 fast field.

The vals_reader will access the concatenated list of all values for all reader. The idx_reader associated, for each document, the index of its first value.

Implementations

source

impl<Item: FastValue> MultiValuedFastFieldReader<Item>

source

pub fn get_vals(&self, doc: DocId, vals: &mut Vec<Item>)

Returns the array of values associated to the given doc.

source

pub fn min_value(&self) -> Item

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 mimimum value.

source

pub fn max_value(&self) -> Item

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.

source

pub fn num_vals(&self, doc: DocId) -> usize

Returns the number of values associated with the document DocId.

source

pub fn total_num_vals(&self) -> u64

Returns the overall number of values in this field .
