Struct sp_state_machine::ProofRecorder [−][src]
pub struct ProofRecorder<Hash> { /* fields omitted */ }
Expand description
Global proof recorder, act as a layer over a hash db for recording queried data.
Implementations
Returns the estimated encoded size of the proof.
The estimation is maybe bigger (by in maximum 4 bytes), but never smaller than the actual encoded proof.
Convert into a StorageProof
.
Trait Implementations
