Struct DownloadClaim 

pub struct DownloadClaim {
    file_upload_id: Uuid,
    exp: usize,
    iat: usize,
}

Authorizes the bearer to read one specific host-stored file for a while.

Minted by the host wherever it hands out a URL for a file-typed answer: to an exercise service’s grade endpoint, and to the views that render a submission. The read-side mirror of UploadClaim; unlike it, this claim names a single file rather than a namespace, so a holder cannot reach any other file.

Fields

file_upload_id: Uuid

exp: usize

iat: usize

Implementations

impl DownloadClaim

pub fn file_upload_id(&self) -> Uuid

pub fn expiring_in_1_day(file_upload_id: Uuid) -> DownloadClaim

A day, not the grading request’s 120 s: a service may finish asynchronously through grading_update_url long after the request returns.

pub fn expiring_in_1_hour(file_upload_id: Uuid) -> DownloadClaim

For a URL a person is about to click: long enough to leave the page open for a while, short enough that a copied link is not a lasting handle on someone else’s answer.

pub fn sign(self, key: &JwtKey) -> Result<String, Error>

pub fn validate(token: &str, key: &JwtKey) -> Result<DownloadClaim, Error>
