Struct Cmr 

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

Commitment Merkle root

A Merkle root that commits to a node’s combinator and recursively its children.

Importantly, witness data and right disconnect branches are not included in the hash. This makes these elements malleable while preserving program identity (SegWit, delegation).

Uniquely identifies a program’s structure in terms of combinators at commitment time.

Implementations

impl Cmr

pub const fn from_byte_array(data: [u8; 32]) -> Self
