Example

const PKB: usize = emerald_rs::PRIVATE_KEY_BYTES;
let pk = emerald_rs::PrivateKey::try_from(&[0u8; PKB]).unwrap();
assert_eq!(pk.to_string(),

Trait Implementations

impl Clone for PrivateKey

fn clone(&self) -> PrivateKey

Returns a copy of the value.

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

impl Ord for PrivateKey

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.
