Struct PackageDigest 

pub struct PackageDigest {
    pub algorithm: DigestAlgorithm,
    pub value: String,
}

The digest a downloaded package must match.

Fields

algorithm: DigestAlgorithm

value: String

Lower-case hexadecimal.

Implementations

impl PackageDigest

pub fn sha256(value: impl AsRef<str>) -> Self

A SHA-256 digest, from hexadecimal in either case.

pub fn parse(value: &str) -> Option<Self>

Reads the sha256:<hex> form release feeds publish.

pub fn is_well_formed(&self) -> bool

Whether this digest could be one: the right length, and hexadecimal.

A malformed digest is refused before a download starts rather than after it, so nobody waits for two hundred megabytes to learn the release feed was misconfigured.

pub fn to_feed_string(&self) -> String

The sha256:<hex> form.
