Struct flow_sdk::algorithms::secp256k1::secp256k1_sys::Signature

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

Library-internal representation of a Secp256k1 signature

Implementations

impl Signature

pub unsafe fn new() -> Signature

Creates an “uninitialized” FFI signature which is zeroed out

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]) -> Signature

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

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 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 Signature

pub fn as_ptr(&self) -> *const u8

Converts the object to a raw pointer for FFI interfacing

pub fn as_mut_ptr(&mut self) -> *mut u8

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
