Struct PrefixOf 

struct PrefixOf<'a> {
    prefix_of: &'a [u8],
}

Implements [fst::Automaton]

It will match if prefix_of is a prefix of the given data.

Fields

prefix_of: &'a [u8]

Implementations

impl<'a> PrefixOf<'a>

fn new(prefix_of: &'a [u8]) -> Self

Creates a new PrefixOf from the given slice.

Trait Implementations

impl Automaton for PrefixOf<'_>

type State = usize

The type of the state used in the automaton.

fn start(&self) -> usize

Returns a single start state for this automaton.

fn is_match(&self, state: &usize) -> bool

Returns true if and only if state is a match state.

fn can_match(&self, state: &usize) -> bool

Returns true if and only if state can lead to a match in zero or more steps.

fn accept(&self, state: &usize, byte: u8) -> usize

Return the next state given state and an input.

fn will_always_match(&self, _state: &Self::State) -> bool

Returns true if and only if state matches and must match no matter what steps are taken.

fn accept_eof(&self, _: &Self::State) -> Option<Self::State>

If applicable, return the next state when the end of a key is seen.

fn starts_with(self) -> StartsWith<Self>

where Self: Sized,

Returns an automaton that matches the strings that start with something this automaton matches.

fn union<Rhs>(self, rhs: Rhs) -> Union<Self, Rhs>

where Rhs: Automaton, Self: Sized,

Returns an automaton that matches the strings matched by either this or the other automaton.

fn intersection<Rhs>(self, rhs: Rhs) -> Intersection<Self, Rhs>

where Rhs: Automaton, Self: Sized,

Returns an automaton that matches the strings matched by both this and the other automaton.

fn complement(self) -> Complement<Self>

where Self: Sized,

Returns an automaton that matches the strings not matched by this automaton.
