Struct bitcoin::key::secp256k1::ffi::PublicKey

pub struct PublicKey(_);

Library-internal representation of a Secp256k1 public key

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.

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.

Trait Implementations

impl AsRef<[u8; 64]> for PublicKey

fn as_ref(&self) -> &[u8; 64]

Gets a reference to the underlying array

impl CPtr for PublicKey

type Target = u8

fn as_c_ptr(&self) -> *const <PublicKey as CPtr>::Target

fn as_mut_c_ptr(&mut self) -> *mut <PublicKey as CPtr>::Target

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<PublicKey> for PublicKey

Creates a new public key from a FFI public key.

Note, normal users should never need to interact directly with FFI types.

fn from(pk: PublicKey) -> PublicKey

Converts to this type from the input type.

impl Hash for PublicKey

fn hash<H>(&self, state: &mut H)where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<I> Index<I> for PublicKeywhere [u8]: Index<I>,

type Output = <[u8] as Index<I>>::Output

The returned type after indexing.

fn index(&self, index: I) -> &<PublicKey as Index<I>>::Output

Performs the indexing (container[index]) operation.

impl Ord for PublicKey

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

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<PublicKey> for PublicKey

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

impl PartialOrd<PublicKey> for PublicKey

fn partial_cmp(&self, other: &PublicKey) -> 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.

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

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

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

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

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

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