Struct fst::map::StreamBuilder

pub struct StreamBuilder<'m, A = AlwaysMatch>(_);

A builder for constructing range queries on streams.

Once all bounds are set, one should call into_stream to get a Stream.

Bounds are not additive. That is, if ge is called twice on the same builder, then the second setting wins.

The A type parameter corresponds to an optional automaton to filter the stream. By default, no filtering is done.

The 'm lifetime parameter refers to the lifetime of the underlying map.

Methods

impl<'m, A: Automaton> StreamBuilder<'m, A>

fn ge<T: AsRef<[u8]>>(self, bound: T) -> Self

Specify a greater-than-or-equal-to bound.

fn gt<T: AsRef<[u8]>>(self, bound: T) -> Self

Specify a greater-than bound.

fn le<T: AsRef<[u8]>>(self, bound: T) -> Self

Specify a less-than-or-equal-to bound.

fn lt<T: AsRef<[u8]>>(self, bound: T) -> Self

Specify a less-than bound.

Trait Implementations

impl<'m, 'a, A: Automaton> IntoStreamer<'a> for StreamBuilder<'m, A>

type Item = (&'a [u8], u64)

The type of the item emitted by the stream.

type Into = Stream<'m, A>
