Struct secp256k1_sys::Signature

#[repr(C)]
pub struct Signature(_);

Library-internal representation of a Secp256k1 signature

Implementations

impl Signature

pub fn as_ptr(&self) -> *const c_uchar

Converts the object to a raw pointer for FFI interfacing

pub fn as_mut_ptr(&mut self) -> *mut c_uchar

Converts the object to a mutable raw pointer for FFI interfacing

pub fn len(&self) -> usize

Returns the length of the object as an array

pub fn is_empty(&self) -> bool

Returns whether the object as an array is empty

impl Signature

pub unsafe fn new() -> Self

Creates an “uninitialized” FFI signature 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; 64]) -> Self

Create a new signature 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; 64]

Returns the underlying FFI opaque representation of the signature

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

impl Index<Range<usize>> for Signature

type Output = [u8]

The returned type after indexing.

fn index(&self, index: Range<usize>) -> &[c_uchar]

Performs the indexing (container[index]) operation.

impl Index<RangeFrom<usize>> for Signature

type Output = [u8]

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl Index<RangeFull> for Signature

type Output = [u8]

The returned type after indexing.

fn index(&self, _: RangeFull) -> &[c_uchar]

Performs the indexing (container[index]) operation.

impl Index<RangeTo<usize>> for Signature

type Output = [u8]

fn index(&self, index: RangeTo<usize>) -> &[c_uchar]

Performs the indexing (container[index]) operation.

impl Index<usize> for Signature

type Output = u8

The returned type after indexing.

fn index(&self, index: usize) -> &c_uchar

Performs the indexing (container[index]) operation.

impl Ord for Signature

fn cmp(&self, other: &Signature) -> 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<Signature> for Signature

fn eq(&self, other: &Signature) -> 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<Signature> for Signature

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