Struct Sha256Digest 

pub struct Sha256Digest(/* private fields */);

A SHA-256 digest written as sha256: followed by 64 lowercase hex digits.

The one hash encoding in the transcript. Parsing rejects any other form, so a recorded digest compares correctly as a string.

Implementations

impl Sha256Digest

pub fn of(data: &[u8]) -> Self

The digest of data.

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

The written form of a raw 32-byte digest.

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

The raw 32 bytes.

pub fn parse(s: &str) -> Result<Self, DigestFormatError>

Parse a digest in its written form.

use rite_model::Sha256Digest;

let digest = Sha256Digest::of(b"ceremony");
assert_eq!(Sha256Digest::parse(digest.as_str()), Ok(digest));
// Any other spelling is refused.
assert!(Sha256Digest::parse("SHA256:00").is_err());

Errors

Returns DigestFormatError unless s is sha256: followed by exactly 64 lowercase hex digits.

pub fn as_str(&self) -> &str

The written form, sha256:<hex>.
