Struct serde_urlencoded::de::Deserializer

pub struct Deserializer<'a> { /* fields omitted */ }

A deserializer for the application/x-www-form-urlencoded format.

• Supported top-level outputs are structs, maps and sequences of pairs, with or without a given length.

• Main deserialize methods defers to deserialize_map.

• Everything else but deserialize_seq and deserialize_seq_fixed_size defers to deserialize.

Methods

impl<'a> Deserializer<'a>

pub fn new(parser: UrlEncodedParse<'a>) -> Self

Returns a new Deserializer.

fn deserialize_str<__V>(self, visitor: __V) -> Result<__V::Value, Self::Error> where
    __V: Visitor, 

Hint that the Deserialize type is expecting a string value and does not benefit from taking ownership of buffered data owned by the Deserializer.

fn deserialize_string<__V>(
    self,
    visitor: __V

    __V: Visitor, 

Hint that the Deserialize type is expecting a string value and would benefit from taking ownership of buffered data owned by the Deserializer.

    self,
    visitor: __V
) -> Result<__V::Value, Self::Error> where
    __V: Visitor, 

Hint that the Deserialize type is expecting an optional value.

fn deserialize_bytes<__V>(self, visitor: __V) -> Result<__V::Value, Self::Error> where
    __V: Visitor, 

Hint that the Deserialize type is expecting a byte array and does not benefit from taking ownership of buffered data owned by the Deserializer.

    self,
    visitor: __V
) -> Result<__V::Value, Self::Error> where
    __V: Visitor, 

Hint that the Deserialize type is expecting a byte array and would benefit from taking ownership of buffered data owned by the Deserializer.

fn deserialize_unit_struct<__V>(
    self,
    _: &'static str,
    visitor: __V
) -> Result<__V::Value, Self::Error> where
    __V: Visitor, 

Hint that the Deserialize type is expecting a unit struct with a particular name.
