Struct Commitment 

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

A binding, hiding commitment to a Contribution. Public.

Compared with plain ==: both sides are public values, so timing leaks nothing. Debug and Display print lowercase hex.

Implementations

impl Commitment

pub const fn from_bytes(bytes: [u8; 32]) -> Self

Wraps raw digest bytes. Used by the other commitment constructors in this module; a caller has no reason to build one by hand.

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

The 32 digest bytes.

pub fn to_hex(&self) -> String

Lowercase hex, 64 characters.

pub fn from_hex(s: &str) -> Result<Self, CardError>

Parses 64 hex digits of either case.

Errors

CardError::InvalidHex with the offending input on wrong length or a non-hex character.

pub fn verify(&self, c: &Contribution) -> bool

Recompute the commitment of c and compare.
