Decoder of CBOR map

Required Methods

fn size(&self) -> Option<usize>

Number of entries of the map being decoded (total number of entries, not remaining). Returns None if the map has indefinite size.

fn deserialize_key<K>(&mut self) -> Result<Option<K>, CborSerializationError>

where K: CborDeserialize,

Deserialize an entry key. Returns None if all entries in the map has been deserialized.

fn deserialize_value<V>(&mut self) -> Result<V, CborSerializationError>

where V: CborDeserialize,

Deserialize an entry value.

fn skip_value(&mut self) -> Result<(), CborSerializationError>

Skips entry value

Provided Methods

fn deserialize_entry<K, V>( &mut self, ) -> Result<Option<(K, V)>, CborSerializationError>

where K: CborDeserialize, V: CborDeserialize,

Deserialize an entry consisting of a key and value. Returns None if all entries in the map has been deserialized. The total number of entries that can be deserialized is equal to Self::size.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
