pub struct JsonParser<'de> { /* private fields */ }

Streaming JSON parser backed by facet-json’s SliceAdapter.

Implementations

impl<'de> JsonParser<'de>

pub fn new(input: &'de [u8]) -> Self

Trait Implementations

impl<'de> FormatParser<'de> for JsonParser<'de>

type Error = JsonError

Parser-specific error type.

type Probe<'a> = JsonProbe<'de> where Self: 'a

Evidence cursor type produced by FormatParser::begin_probe.

fn raw_capture_shape(&self) -> Option<&'static Shape>

Returns the shape of the format’s raw capture type (e.g., RawJson::SHAPE).

fn next_event(&mut self) -> Result<Option<ParseEvent<'de>>, Self::Error>

Read the next parse event, or None if the input is exhausted.

fn peek_event(&mut self) -> Result<Option<ParseEvent<'de>>, Self::Error>

Peek at the next event without consuming it, or None if at EOF.

fn skip_value(&mut self) -> Result<(), Self::Error>

Skip the current value (for unknown fields, etc.).

fn begin_probe(&mut self) -> Result<Self::Probe<'_>, Self::Error>

Begin evidence collection for untagged-enum resolution.

fn capture_raw(&mut self) -> Result<Option<&'de str>, Self::Error>

Capture the raw representation of the current value without parsing it.

fn is_self_describing(&self) -> bool

Returns true if this format is self-describing.

fn hint_struct_fields(&mut self, _num_fields: usize)

Hint to the parser that a struct with the given number of fields is expected.

fn hint_scalar_type(&mut self, _hint: ScalarTypeHint)

Hint to the parser what scalar type is expected next.

fn hint_sequence(&mut self)

Hint to the parser that a sequence (array/Vec) is expected.

fn hint_array(&mut self, _len: usize)

Hint to the parser that a fixed-size array is expected.

fn hint_option(&mut self)

Hint to the parser that an Option<T> is expected.

fn hint_map(&mut self)

Hint to the parser that a map is expected.

fn hint_enum(&mut self, _variants: &[EnumVariantHint])

Hint to the parser that an enum is expected, providing variant information.

fn hint_opaque_scalar( &mut self, _type_identifier: &'static str, _shape: &'static Shape, ) -> bool

Hint to the parser that an opaque scalar type is expected.

fn current_span(&self) -> Option<Span>

Returns the source span of the most recently consumed event.
