Trait Implementations

impl Clone for EcdsaKeypair

fn clone(&self) -> EcdsaKeypair

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ConstantTimeEq for EcdsaKeypair

fn ct_eq(&self, other: &Self) -> Choice

Determine if two items are equal.

fn ct_ne(&self, other: &Self) -> Choice

Determine if two items are NOT equal.

impl Debug for EcdsaKeypair

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

Formats the value using the given formatter.

impl Decode for EcdsaKeypair

type Error = Error

Type returned in the event of a decoding error.

fn decode(reader: &mut impl Reader) -> Result<Self>

Attempt to decode a value of this type using the provided Reader.

impl Encode for EcdsaKeypair

fn encoded_len(&self) -> Result<usize>

Get the length of this type encoded in bytes, prior to Base64 encoding.

fn encode(&self, writer: &mut impl Writer) -> Result<()>

Encode this value using the provided Writer.

fn encoded_len_prefixed(&self) -> Result<usize, Error>

Return the length of this type after encoding when prepended with a uint32 length prefix.

fn encode_prefixed(&self, writer: &mut impl Writer) -> Result<(), Error>

Encode this value, first prepending a uint32 length prefix set to Encode::encoded_len.

impl From<&EcdsaKeypair> for EcdsaPublicKey

fn from(keypair: &EcdsaKeypair) -> EcdsaPublicKey

Converts to this type from the input type.

impl From<EcdsaKeypair> for EcdsaPublicKey

fn from(keypair: EcdsaKeypair) -> EcdsaPublicKey

Converts to this type from the input type.

impl From<EcdsaKeypair> for KeypairData

fn from(keypair: EcdsaKeypair) -> KeypairData

Converts to this type from the input type.

impl From<EcdsaKeypair> for PrivateKey

fn from(keypair: EcdsaKeypair) -> PrivateKey

impl PartialEq for EcdsaKeypair

fn eq(&self, other: &Self) -> 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.
