Struct Bip340 

pub struct Bip340(/* private fields */);

An opaque 32-byte cryptographic identifier.

Very similar to the AccountId32, but it is purposely different as it does not implement the SS58 codec.

Implementations

impl Bip340

pub const fn new(inner: [u8; 32]) -> Self

Create a new instance from its raw inner byte value.

Equivalent to this types From<[u8; 32]> implementation. For the lack of const support in traits we have this constructor.
