Methods

impl Key

pub fn local(seed: [u8; 32], key_bytes: &[u8]) -> Self

pub fn type_string(&self) -> String

pub fn serialized_size(&self) -> usize

Calculates serialized size without actually serializing data.

pub const fn serialized_size_hint() -> usize

Returns max size a Key can be serialized into.

impl Key

pub fn to_turef<T: CLTyped>(self) -> Option<TURef<T>>

pub fn to_contract_ref(self) -> Option<ContractRef>

pub fn as_account(&self) -> Option<[u8; 32]>

Returns bytes of an account

pub fn normalize(self) -> Key

pub fn parse_hash(hex_encodede_hash: &str) -> Option<Key>

Creates an instance of Key::Hash from the hex-encoded string. Returns None if hex_encodede_hash does not decode to a 32-byte array.

pub fn parse_uref(
    hex_encoded_uref: &str,
    access_rights: AccessRights
) -> Option<Key>

Creates an instance of Key::URef from the hex-encoded string. Returns None if hex_encoded_uref does not decode to a 32-byte array.

pub fn parse_local(
    hex_encoded_seed: &str,
    hex_encoded_key_bytes: &str
) -> Option<Key>

Creates an instance of Key::Local from the hex-encoded strings. Returns None if hex_encoded_seed does not decode to a 32-byte array, or if hex_encoded_key_bytes does does not decode from hex.

pub fn as_string(&self) -> String

pub fn as_uref(&self) -> Option<&URef>

pub fn into_uref(self) -> Option<URef>

pub fn as_hash(&self) -> Option<[u8; 32]>

pub fn as_local(&self) -> Option<[u8; 32]>
