impl Index<RangeFrom<usize>> for SecretKey

type Output = [u8]

The returned type after indexing.

fn index(&self, index: RangeFrom<usize>) -> &[u8]

Performs the indexing (container[index]) operation.

impl Index<RangeFull> for SecretKey

impl Ord for SecretKey

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

This method returns an Ordering between self and other.

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

where Self: Sized,

impl PartialEq for SecretKey

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

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

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

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

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

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

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

impl Zeroize for SecretKey

fn zeroize(&mut self)
