Implementations

impl Utils

pub fn public_key_rand() -> [u8; 32]

Generate a public key from random bytes. This is useful for testing

pub fn rand_32bytes() -> [u8; 32]

Generate a 32 byte array from random bytes

pub fn jsvalue_to_error<T: Debug>( value: Result<T, JsValue>, ) -> Result<(), WalletError>

Convert a JsValue error to a WalletError

pub fn public_key(public_key_bytes: [u8; 32]) -> WalletResult<VerifyingKey>

Parse a PublicKey from an array of 32 bytes

pub fn signature(signature_bytes: [u8; 64]) -> Signature

Parse a Signature from an array of 64 bytes

pub fn to32byte_array(bytes: &[u8]) -> WalletResult<[u8; 32]>

Convert a slice of bytes into a 32 byte array. This is useful especially if a PublicKey is given as a slice instead of 32 byte array

pub fn to64byte_array(bytes: &[u8]) -> WalletResult<[u8; 64]>

Convert a slice of bytes into a 64 byte array. This is useful especially if a Signature is given as a slice instead of 64 byte array

pub fn verify_signature( public_key: VerifyingKey, message: &[u8], signature: Signature, ) -> WalletResult<()>

Verify a message using a PublicKey and Signature

pub fn jsvalue_to_signature( value: JsValue, namespace: &str, ) -> WalletResult<Signature>

Convert a JsValue to a Signature

pub fn address(public_key: VerifyingKey) -> String

Generate the Base58 address from a PublicKey

pub fn base58_signature(signature: Signature) -> String

Generate a Base58 encoded string from a Signature

pub fn shorten_base58(base58_str: &str) -> WalletResult<Cow<'_, str>>

Get the shortened string of the Base58 string . It displays the first 4 characters and the last for characters separated by ellipsis eg FXdl...RGd4 . If the string is less than 8 characters, an error is thrown

pub fn custom_shorten_base58( base58_str: &str, take: usize, ) -> WalletResult<Cow<'_, str>>

Same as Self::shorten_base58 but with a custom range instead of taking the first 4 character and the last 4 characters it uses a custom range.
