Struct MainEngine

pub struct MainEngine { /* private fields */ }

Main engine for a fixed JSONPath query.

The engine is stateless, meaning that it can be executed on any number of separate inputs, even on separate threads.

Trait Implementations

impl Compiler for MainEngine

type E = MainEngine

Concrete type of the Engines created, parameterized with the lifetime of the input query.

fn compile_query(query: &JsonPathQuery) -> Result<Self, CompilerError>

Compile a JsonPathQuery into an Engine.c

fn from_compiled_query(automaton: Automaton) -> Self::E

Turn a compiled Automaton into an Engine.

impl Engine for MainEngine

fn count<I>(&self, input: &I) -> Result<MatchCount, EngineError>

where I: Input,

Find the number of matches on the given Input.

fn indices<I, S>(&self, input: &I, sink: &mut S) -> Result<(), EngineError>

where I: Input, S: Sink<MatchIndex>,

Find the starting indices of matches on the given Input and write them to the Sink.

fn approximate_spans<I, S>( &self, input: &I, sink: &mut S, ) -> Result<(), EngineError>

where I: Input, S: Sink<MatchSpan>,

Find the approximate spans of matches on the given Input and write them to the Sink.

fn matches<I, S>(&self, input: &I, sink: &mut S) -> Result<(), EngineError>

where I: Input, S: Sink<Match>,
