Enum Credential 

#[non_exhaustive]
pub enum Credential<'a> {
    Anonymous,
    Bearer(Cow<'a, str>),
    Header {
        name: &'static str,
        value: Cow<'a, str>,
    },
    Presigned,
}

The credential to apply to a request, returned cheaply (often borrowed) per fetch.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Anonymous

No credential (public resource).

Bearer(Cow<'a, str>)

Authorization: Bearer <token>.

Header

A custom header name: value (e.g. x-api-key).

Fields

name: &'static str

The header name.

value: Cow<'a, str>

The header value.

Presigned

The URL is already signed; send it verbatim with no added credential.
