Struct Checksum 

pub struct Checksum {
    pub algorithm: ChecksumAlgorithm,
    pub value: String,
}

A checksum algorithm and its canonical lowercase hexadecimal value.

Fields

algorithm: ChecksumAlgorithm

Algorithm that produced value.

value: String

The canonical lowercase hexadecimal checksum without a prefix.

Implementations

impl Checksum

pub fn compute(algorithm: ChecksumAlgorithm, bytes: &[u8]) -> Self

Builds the algorithm checksum for these complete bytes.

The one-shot forms below are this with the algorithm spelled out, so a payload held whole and one delivered in pieces cannot drift: both close the same digest.

pub fn sha256(bytes: &[u8]) -> Self

Builds the SHA-256 checksum for these bytes.

pub fn crc64nvme(bytes: &[u8]) -> Self

Builds the CRC-64/NVME checksum for these bytes.

pub fn crc32c(bytes: &[u8]) -> Self

Builds the CRC-32C checksum for these bytes.

pub fn matches(&self, bytes: &[u8]) -> bool

Reports whether these bytes produce this exact checksum.

pub fn validate(&self) -> Result<(), ChecksumValidationError>

Validates the exact width and lowercase-hex alphabet for algorithm.
