Struct secp256k1_sys::Keypair

#[repr(C)]
pub struct Keypair(/* private fields */);

Implementations

impl Keypair

pub fn cmp_fast_unstable(&self, other: &Self) -> 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: &Self) -> 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 Keypair

pub unsafe fn new() -> Self

Creates an “uninitialized” FFI keypair which is zeroed out

Safety

If you pass this to any FFI functions, except as an out-pointer, the result is likely to be an assertation failure and process termination.

pub unsafe fn from_array_unchecked(data: [c_uchar; 96]) -> Self

Create a new keypair usable for the FFI interface from raw bytes

Safety

Does not check the validity of the underlying representation. If it is invalid the result may be assertation failures (and process aborts) from the underlying library. You should not use this method except with data that you obtained from the FFI interface of the same version of this library.

pub fn underlying_bytes(self) -> [c_uchar; 96]

Returns the underlying FFI opaque representation of the x-only public key

You should not use this unless you really know what you are doing. It is essentially only useful for extending the FFI interface itself.

pub fn non_secure_erase(&mut self)

Attempts to erase the contents of the underlying array.

Note, however, that the compiler is allowed to freely copy or move the contents of this array to other places in memory. Preventing this behavior is very subtle. For more discussion on this, please see the documentation of the zeroize crate.

impl Ord for Keypair

Available on non-secp256k1_fuzz only.

fn cmp(&self, other: &Keypair) -> 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.
