Struct identity_iota::account_storage::KeyLocation

pub struct KeyLocation {
    pub key_type: KeyType,
    /* private fields */
}

Available on crate feature account only.

The storage location of a verification method key.

A key is uniquely identified by the fragment and a hash of its public key. Importantly, the fragment alone is insufficient to represent the storage location. For example, when rotating a key, there will be two keys in storage for the same identity with the same fragment. The key_hash disambiguates the keys in situations like these.

The string representation of that location can be obtained via canonical_repr.

Fields

key_type: KeyType

The KeyType of the key.

Implementations

impl KeyLocation

pub fn new(
    key_type: KeyType,
    fragment: String,
    public_key: &[u8]
) -> KeyLocation

Create a location from a KeyType, the fragment of a verification method and the bytes of a public key.

pub fn from_verification_method(
    method: &VerificationMethod<IotaDID, BTreeMap<String, Value, Global>>
) -> Result<KeyLocation, Error>

Obtain the location of a verification method’s key in storage.

pub fn canonical(&self) -> String

Returns the canonical string representation of the location.

This should be used as the representation for storage keys.
