Implementations§

§

impl PublicKey

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

pub unsafe fn new() -> PublicKey

Creates an “uninitialized” FFI public key 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: [u8; 64]) -> PublicKey

Create a new public key 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) -> [u8; 64]

Returns the underlying FFI opaque representation of the 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.
