Trait Implementations

impl Clone for ECDSASignature

fn clone(&self) -> ECDSASignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ECDSASignature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ECDSASignature

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserializes the signature from a string or bytes.

impl Display for ECDSASignature

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

Writes the signature as a hex string.

impl FromBytes for ECDSASignature

fn read_le<R: Read>(reader: R) -> IoResult<Self>

Reads Self from reader as little-endian bytes.

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

where Self: Sized,

Returns Self from a byte array in little-endian order.

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

where Self: Sized,

Same behavior as Self::from_bytes_le but avoids costly checks. This shall only be called when deserializing from a trusted source, such as local storage.

fn read_le_unchecked<R>(reader: R) -> Result<Self, Error>

where R: Read, Self: Sized,

Same behavior as Self::read_le but avoids costly checks. This shall only be called when deserializing from a trusted source, such as local storage.

fn read_le_with_unchecked<R>(reader: R, unchecked: bool) -> Result<Self, Error>

where R: Read, Self: Sized,

Helper function that deserializes either unchecked or checked based on the given boolean flag.

impl FromStr for ECDSASignature

fn from_str(signature: &str) -> Result<Self, Self::Err>

Parses a hex-encoded string into an ECDSASignature.

type Err = Error

The associated error which can be returned from parsing.

impl PartialEq for ECDSASignature

fn eq(&self, other: &ECDSASignature) -> 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 Serialize for ECDSASignature

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serializes the signature into string or bytes.

impl ToBytes for ECDSASignature

fn write_le<W: Write>(&self, writer: W) -> IoResult<()>
