Struct serde_cbor::de::Deserializer

pub struct Deserializer<R: Read> {
    // some fields omitted
}

A structure that deserializes CBOR into Rust values.

Methods

impl<R: Read> Deserializer<R>

fn new(reader: R) -> Deserializer<R>

Creates the CBOR parser from an std::io::Read.

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

The Deserializer::end method should be called after a value has been fully deserialized. This allows the Deserializer to validate that the input stream is at the end.

Trait Implementations

impl<R: Read> Deserializer for Deserializer<R>

type Error = Error

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

fn deserialize<V: Visitor>(&mut self, visitor: V) -> Result<V::Value>

This method hints that the Deserialize type is expecting an unit value.

fn deserialize_seq<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a sequence value. This allows deserializers to parse sequences that aren't tagged as sequences.

fn deserialize_fixed_size_array<V>(&mut self, _len: usize, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

fn deserialize_map<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a map of values. This allows deserializers to parse sequences that aren't tagged as maps.

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

This method hints that the Deserialize type is expecting a unit struct. This allows deserializers to a unit struct that aren't tagged as a unit struct.

fn deserialize_newtype_struct<V>(&mut self, name: &'static str, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a newtype struct. This allows deserializers to a newtype struct that aren't tagged as a newtype struct.

fn deserialize_struct_field<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting some sort of struct field name. This allows deserializers to choose between &str, usize, or &[u8] to properly deserialize a struct field.

fn deserialize_tuple<V>(&mut self, _len: usize, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

This method hints that the Deserialize type is expecting a tuple value. This allows deserializers that provide a custom tuple serialization to properly deserialize the type.

This method hints that the Deserialize type is expecting an enum value. This allows deserializers that provide a custom enumeration serialization to properly deserialize the type.

fn deserialize_ignored_any<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error> where V: Visitor

impl<R: Read> Read for Deserializer<R>

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chars(self) -> Chars<Self>

Unstable (io)

: the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an Iterator over chars.

fn chain<R>(self, next: R) -> Chain<Self, R> where R: Read

Creates an adaptor which will chain this stream with another.
