Struct serde_json_core::de::Deserializer

pub struct Deserializer<'b> { /* private fields */ }

A structure that deserializes Rust values from JSON in a buffer.

Implementations

impl<'a> Deserializer<'a>

pub fn new(slice: &'a [u8]) -> Deserializer<'_>

Create a new Deserializer

pub fn end(&mut self) -> Result<usize>

Check whether there is any unexpected data left in the buffer and return the amount of data consumed

Trait Implementations

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

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

Unsupported. Can’t parse a value without knowing its expected type.

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

Unsupported. String is not available in no-std.

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

Used to throw out fields from JSON objects that we don’t want to keep in our structs.

type Error = Error

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

fn deserialize_i64<V>(self, visitor: V) -> Result<V::Value>where V: Visitor<'de>,

Hint that the Deserialize type is expecting an i64 value.

fn deserialize_u8<V>(self, visitor: V) -> Result<V::Value>where V: Visitor<'de>,

Hint that the Deserialize type is expecting a u8 value.

fn deserialize_u16<V>(self, visitor: V) -> Result<V::Value>where V: Visitor<'de>,

Hint that the Deserialize type is expecting a u16 value.

Hint that the Deserialize type is expecting a u32 value.

fn deserialize_u64<V>(self, visitor: V) -> Result<V::Value>where V: Visitor<'de>,

Hint that the Deserialize type is expecting a u64 value.

fn deserialize_f32<V>(self, visitor: V) -> Result<V::Value>where V: Visitor<'de>,

Hint that the Deserialize type is expecting a f32 value.

fn deserialize_f64<V>(self, visitor: V) -> Result<V::Value>where V: Visitor<'de>,

Hint that the Deserialize type is expecting a f64 value.

fn deserialize_char<V>(self, _visitor: V) -> Result<V::Value>where 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_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>,

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.
