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

Record the given key => val combination.

Returns the value at the given key.

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.

Reset the internal state.
