Struct SubspaceId 

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

The type of SubspaceIds used by Willow’25.

This is a thin wrapper around [u8; SUBSPACE_ID_WIDTH].

use willow25::prelude::*;

let subspace_id = SubspaceId::from([17; SUBSPACE_ID_WIDTH]);
assert_eq!(subspace_id.as_bytes(), &[17; 32]);

Implementations

impl SubspaceId

pub fn as_bytes(&self) -> &[u8; 32]

Returns the raw bytes that make up this subspace id.

This type deliberately does not provide implementations of AsRef, Deref or Borrow, to make it more difficult to leak information accidentally. Apologies if this is inconvenient.
