Struct TaskSignature 

pub struct TaskSignature {
    pub algorithm: SignatureAlgorithm,
    pub tag: String,
}

A computed task signature: the algorithm plus the hex-encoded MAC tag.

This is a serializable value that can be attached to a task message (for example, in a header or sidecar field) and round-tripped through any of the crate’s serializers.

Fields

algorithm: SignatureAlgorithm

MAC algorithm used to produce tag.

tag: String

Lower-case hex encoding of the MAC tag.

Implementations

impl TaskSignature

pub fn hmac_sha256(tag: &[u8]) -> Self

Construct an HMAC-SHA256 signature from raw tag bytes.

pub fn tag_bytes(&self) -> Result<Vec<u8>, SignatureError>

Decode the hex tag back into raw bytes.

Errors

Returns SignatureError::MalformedSignature if the hex is invalid.
