Struct TaskProvenance 

pub struct TaskProvenance { /* private fields */ }

An origin paired with the trust class derived from it.

Both fields are private and the only constructor is Self::derive, so there is no way to pair an origin with a trust class that does not follow from it.

Implementations

impl TaskProvenance

pub fn derive(origin: TaskOrigin, inherited: Option<TrustClass>) -> Self

Derive the trust class for origin.

inherited is the trust of the sending capsule’s own current task, and is consulted only for TaskOrigin::Peer and TaskOrigin::Completion — the two origins that cross a capsule boundary. Passing None for either means the sender made no claim, which resolves to TrustClass::Untrusted: an absent claim is not a trusted one, so untrust cannot launder itself by dropping the header at the first hop.

pub fn origin(&self) -> TaskOrigin

pub fn trust(&self) -> TrustClass
