Struct bitcoin::key::secp256k1::ffi::recovery::RecoverableSignature

pub struct RecoverableSignature(_);

Library-internal representation of a Secp256k1 signature + recovery ID

Implementations

impl RecoverableSignature

pub fn cmp_fast_unstable(&self, other: &RecoverableSignature) -> Ordering

Like cmp::Ord but faster and with no guarantees across library versions.

The inner byte array of Self is passed across the FFI boundry, as such there are no guarantees on its layout and it is subject to change across library versions, even minor versions. For this reason comparison function implementations (e.g. Ord, PartialEq) take measures to ensure the data will remain constant (e.g., by serializing it to a guaranteed format). This means they may be slow, this function provides a faster comparison if you know that your types come from the same library version.

pub fn eq_fast_unstable(&self, other: &RecoverableSignature) -> bool

Like cmp::Eq but faster and with no guarantees across library versions.

The inner byte array of Self is passed across the FFI boundry, as such there are no guarantees on its layout and it is subject to change across library versions, even minor versions. For this reason comparison function implementations (e.g. Ord, PartialEq) take measures to ensure the data will remain constant (e.g., by serializing it to a guaranteed format). This means they may be slow, this function provides a faster equality check if you know that your types come from the same library version.

impl Ord for RecoverableSignature

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.
