Struct ContextToken 

pub struct ContextToken { /* private fields */ }

A context token tracking data exposure for an object.

Context tokens are append-only: exposure labels can be added but never removed. The token is a base64-encoded Biscuit with an authority block identifying the session and subsequent blocks recording exposure labels.

pub fn has_exposure(&self, label: &ExposureLabel) -> bool
