Struct JsonParser 

pub struct JsonParser<'de, const TRUSTED_UTF8: bool = false> { /* private fields */ }

JSON parser using Scanner directly (no adapter layer).

The const generic TRUSTED_UTF8 controls UTF-8 validation:

• TRUSTED_UTF8=true: skip UTF-8 validation (input came from &str)
• TRUSTED_UTF8=false: validate UTF-8 (input came from &[u8])

Implementations

impl<'de, const TRUSTED_UTF8: bool> JsonParser<'de, TRUSTED_UTF8>

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

Trait Implementations

impl<'de, const TRUSTED_UTF8: bool> FormatParser<'de> for JsonParser<'de, TRUSTED_UTF8>

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

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

fn input(&self) -> Option<&'de [u8]>

Returns the raw input bytes, if available.

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

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

fn next_events( &mut self, buf: &mut VecDeque<ParseEvent<'de>>, limit: usize, ) -> Result<usize, ParseError>

Read multiple parse events into a deque, returning the number of events read.

fn save(&mut self) -> SavePoint

Save the current parser position and start recording events.

fn restore(&mut self, save_point: SavePoint)

Restore to a previous save point, replaying recorded events.

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

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

fn skip_value(&mut self) -> Result<(), ParseError>

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

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

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

fn format_namespace(&self) -> Option<&'static str>

Returns the format namespace for format-specific proxy resolution.

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

Returns the source span of the most recently consumed event.

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_byte_sequence(&mut self) -> bool

Hint to the parser that a byte sequence (Vec<u8>, &[u8], etc.) is expected.

fn hint_remaining_byte_sequence(&mut self) -> bool

Hint to the parser that all remaining input bytes should be consumed as a byte slice.

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_dynamic_value(&mut self)

Hint to the parser that a dynamic value 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.
