Struct StreamDeserializer 

pub struct StreamDeserializer { /* private fields */ }

Reads form data from a stream (see deser::stream).

The stream is a single value (like the body of a request) which is parsed once the whole stream was read. An empty stream is an empty map.

use std::collections::BTreeMap;
use deser_urlencoded::DeserializerConfig;

let mut reader = DeserializerConfig::new().reader(&b"a=1&b=2"[..]);
let value: BTreeMap<String, u32> = reader.read().unwrap().unwrap();
assert_eq!(value["b"], 2);
assert!(reader.read::<BTreeMap<String, u32>>().unwrap().is_none());

Implementations

impl StreamDeserializer

pub fn new() -> StreamDeserializer

Creates a stream deserializer.

pub fn with_config(config: DeserializerConfig) -> StreamDeserializer

Creates a stream deserializer with the given configuration.

pub fn config(&self) -> &DeserializerConfig

Returns the configuration.

Trait Implementations

impl Debug for StreamDeserializer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for StreamDeserializer

fn default() -> Self

Returns the “default value” for a type.

impl StreamDeserializer for StreamDeserializer

fn context(&self) -> Context

Returns the context the values are deserialized in.

fn frame(&mut self, input: &[u8], eof: bool) -> Result<Frame, Error>

Finds the next value in the input.

fn drive_frame<'de>( &mut self, frame: &'de [u8], driver: &mut DeserializeDriver<'_, 'de>, ) -> Result<(), Error>

Deserializes a value from its frame.

fn is_text(&self) -> bool

Returns true if the format is text.

fn supports_partial(&self) -> bool

Returns true if the deserializer implements drive_partial.

fn drive_partial( &mut self, input: &[u8], offset: usize, eof: bool, driver: &mut DeserializeDriver<'_, '_>, ) -> Result<Progress, Error>

Deserializes a value while its input arrives.

fn peek(&mut self, input: &[u8], eof: bool) -> Result<Option<Progress>, Error>

Finds the start of the next value without deserializing it.
