Struct ObligationId 

pub struct ObligationId(pub String);

Stable identifier of an obligation: the canonical JSON of its value.

Two obligations with the same identifier in one view are a map defect (spec §8.4). Parameterized obligations therefore carry their entity ids.

0: String

impl ObligationId

pub fn of<O: Serialize + ?Sized>(obligation: &O) -> Result<Self, HashError>
