Trait Implementations

impl<'a, 'de> Deserializer<'de> for &'a mut Deserializer<'de>

type Error = Error

The error type that can be returned if some error occurs during deserialization.

fn deserialize_any<V>(self, _visitor: V) -> Result<V::Value> where
    V: Visitor<'de>, 

Unsupported. We rely on typed deserialization methods, even if a JSON has enough type information to detect types in many cases.

See https://serde.rs/impl-deserialize.html to learn more about the differentiation between deserialize_{type} and deserialize_any.

    V: Visitor<'de>, 

Hint that the Deserialize type is expecting a char value.

fn deserialize_str<V>(self, visitor: V) -> Result<V::Value> where
    V: Visitor<'de>, 

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) -> Result<V::Value> where
    V: Visitor<'de>, 

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

fn deserialize_bytes<V>(self, _visitor: V) -> Result<V::Value> where
    V: Visitor<'de>, 

Unsupported

fn deserialize_byte_buf<V>(self, _visitor: V) -> Result<V::Value> where
    V: Visitor<'de>, 

Unsupported

fn deserialize_option<V>(self, visitor: V) -> Result<V::Value> where
    V: Visitor<'de>, 

Hint that the Deserialize type is expecting an optional value.

fn deserialize_unit<V>(self, _visitor: V) -> Result<V::Value> where
    V: Visitor<'de>, 

Unsupported. Use a more specific deserialize_* method

fn deserialize_unit_struct<V>(
    self,
    _name: &'static str,
    _visitor: V
) -> Result<V::Value> where
    V: Visitor<'de>, 

Unsupported. Use a more specific deserialize_* method

fn deserialize_newtype_struct<V>(
    self,
    _name: &'static str,
    visitor: V
) -> Result<V::Value> where
    V: Visitor<'de>, 

Unsupported. We can’t parse newtypes because we don’t know the underlying type.

fn deserialize_seq<V>(self, visitor: V) -> Result<V::Value> where
    V: Visitor<'de>, 

Hint that the Deserialize type is expecting a sequence of values.

fn deserialize_tuple<V>(self, _len: usize, visitor: V) -> Result<V::Value> where
    V: Visitor<'de>, 

Hint that the Deserialize type is expecting a sequence of values and knows how many values there are without looking at the serialized data.

fn deserialize_tuple_struct<V>(
    self,
    _name: &'static str,
    _len: usize,
    visitor: V
) -> Result<V::Value> where
    V: Visitor<'de>, 

Hint that the Deserialize type is expecting a tuple struct with a particular name and number of fields.

fn deserialize_map<V>(self, _visitor: V) -> Result<V::Value> where
    V: Visitor<'de>, 

Unsupported. Can’t make an arbitrary-sized map in no-std. Use a struct with a known format, or implement a custom map deserializer / visitor: https://serde.rs/deserialize-map.html

fn deserialize_struct<V>(
    self,
    _name: &'static str,
    _fields: &'static [&'static str],

    V: Visitor<'de>, 

Hint that the Deserialize type is expecting an i128 value.
