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.

Implementations

impl MainEngine

pub fn automaton(&self) -> &Automaton

Get a reference to the underlying compiled query.

Trait Implementations

impl Clone for MainEngine

fn clone(&self) -> MainEngine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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.
