Encode this value using the provided Writer.

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

impl From<&DsaKeypair> for DsaPublicKey

fn from(keypair: &DsaKeypair) -> DsaPublicKey

Converts to this type from the input type.

impl From<DsaKeypair> for DsaPublicKey

fn from(keypair: DsaKeypair) -> DsaPublicKey

fn from(public_key: DsaPublicKey) -> KeyData

Converts to this type from the input type.

impl From<DsaPublicKey> for PublicKey

fn from(public_key: DsaPublicKey) -> PublicKey

Converts to this type from the input type.

impl Ord for DsaPublicKey

fn cmp(&self, other: &DsaPublicKey) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<DsaPublicKey> for DsaPublicKey

fn eq(&self, other: &DsaPublicKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<DsaPublicKey> for DsaPublicKey

fn partial_cmp(&self, other: &DsaPublicKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

const fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

const fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

const fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

const fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
