impl<K> From<&ExtendedPrivateKey<K>> for ExtendedPublicKey<K::PublicKey>

where K: PrivateKey,

fn from(xprv: &ExtendedPrivateKey<K>) -> ExtendedPublicKey<K::PublicKey>

Converts to this type from the input type.

impl From<ExtendedPublicKey<PublicKey>> for XPub

fn from(inner: ExtendedPublicKey<PublicKey>) -> Self

Converts to this type from the input type.

where K: PublicKey,

type Err = Error

The associated error which can be returned from parsing.

fn from_str(xpub: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl<K: Ord + PublicKey> Ord for ExtendedPublicKey<K>

fn cmp(&self, other: &ExtendedPublicKey<K>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<K: PartialEq + PublicKey> PartialEq for ExtendedPublicKey<K>

fn eq(&self, other: &ExtendedPublicKey<K>) -> bool

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

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.

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

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

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

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