Struct ReaderJsonParser

pub struct ReaderJsonParser<R: Read> { /* private fields */ }

Expand description

Parses a JSON file from a Read implementation.

use json_event_parser::{JsonEvent, ReaderJsonParser};

let mut reader = ReaderJsonParser::new(b"{\"foo\": 1}".as_slice());
assert_eq!(reader.parse_next()?, JsonEvent::StartObject);
assert_eq!(reader.parse_next()?, JsonEvent::ObjectKey("foo".into()));
assert_eq!(reader.parse_next()?, JsonEvent::Number("1".into()));
assert_eq!(reader.parse_next()?, JsonEvent::EndObject);
assert_eq!(reader.parse_next()?, JsonEvent::Eof);

Implementations§

impl<R: Read> ReaderJsonParser<R>

pub const fn new(read: R) -> Self

pub fn with_max_buffer_size(self, size: usize) -> Self

Sets the max size of the internal buffer in bytes

pub fn parse_next(&mut self) -> Result<JsonEvent<'_>, JsonParseError>

pub fn read_next_event(&mut self) -> Result<JsonEvent<'_>, JsonParseError>

👎Deprecated: Use parse_next() instead
