Struct BorshCodec

pub struct BorshCodec;

A StateCodec that uses borsh for all keys and values.

Trait Implementations

impl BorshDeserialize for BorshCodec

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for BorshCodec

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for BorshCodec

fn clone(&self) -> BorshCodec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BorshCodec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BorshCodec

fn default() -> BorshCodec

Returns the “default value” for a type.

impl<T> EncodeKeyLike<[T], Vec<T>> for BorshCodec

where T: BorshSerialize,

fn encode_key_like(&self, borrowed: &[T]) -> Vec<u8>

Encodes a reference to Ref as if it were a reference to Target.

impl PartialEq for BorshCodec

fn eq(&self, other: &BorshCodec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StateCodec for BorshCodec

type KeyCodec = BorshCodec

The codec used to serialize keys. See StateKeyCodec.

type ValueCodec = BorshCodec

The codec used to serialize and deserialize values. See StateValueCodec.

fn key_codec(&self) -> &Self::KeyCodec

Returns a reference to the type’s key codec.

fn value_codec(&self) -> &Self::ValueCodec

Returns a reference to the type’s value codec.

impl<K> StateKeyCodec<K> for BorshCodec

where K: BorshSerialize + BorshDeserialize,

fn encode_key(&self, value: &K) -> Vec<u8>

Serializes a key into a bytes vector.

impl<V> StateValueCodec<V> for BorshCodec

where V: BorshSerialize + BorshDeserialize,

type Error = Error

Error type that can arise during deserialization.

fn encode_value(&self, value: &V) -> Vec<u8>

Serializes a value into a bytes vector.

fn try_decode_value(&self, bytes: &[u8]) -> Result<V, Self::Error>

Tries to deserialize a value from a bytes slice, and returns a Result with either the deserialized value or an error.

fn decode_value_unwrap(&self, bytes: &[u8]) -> V

Deserializes a value from a bytes slice.
