}

Callback-based visitor interface for the simdjson tape.

Implement this trait to build custom data structures from the tape without allocating intermediate Value nodes.

Required Associated Types

type Output

The value produced after visiting a complete JSON value.

Required Methods

fn visit_null(&mut self) -> Result<Self::Output>

fn visit_bool(&mut self, v: bool) -> Result<Self::Output>

fn visit_i64(&mut self, v: i64) -> Result<Self::Output>

fn visit_u64(&mut self, v: u64) -> Result<Self::Output>

fn visit_f64(&mut self, v: f64) -> Result<Self::Output>

fn visit_str(&mut self, s: &'a str) -> Result<Self::Output>

Visit a string value. The s borrow is tied to the tape lifetime 'a.

fn visit_array( &mut self, tape: &mut TapeRef<'a>, end_idx: usize, ) -> Result<Self::Output>

Visit an array. The implementor should call tape.visit(self) for each element while tape.pos() < end_idx.

fn visit_object( &mut self, tape: &mut TapeRef<'a>, end_idx: usize, ) -> Result<Self::Output>

Visit an object. Fields are key–value pairs; the implementor should read key strings and call tape.visit(self) for values while tape.pos() < end_idx.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
