Enum SourceExpression 

#[non_exhaustive]
pub enum SourceExpression {
    Scheme(String),
    Host(HostSource),
    Keyword(Keyword),
    Nonce(String),
    Hash(HashExpression),
}

One recognized source-expression alternative (CSP3 §2.3.1).

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.

Scheme(String)

A scheme-source (e.g. https:), without the trailing :.

Host(HostSource)

A host-source.

Keyword(Keyword)

A keyword-source (e.g. 'self').

Nonce(String)

The base64-value from a 'nonce-...' token, without the 'nonce-/' wrapper.

Hash(HashExpression)

A hash-source (e.g. 'sha256-...').
