Struct RecordingProofSizeProvider

Source 
pub struct RecordingProofSizeProvider { /* private fields */ }
Expand description

An implementation of ProofSizeProvider that records the return value of the calls to ProofSizeProvider::estimate_encoded_size.

Wraps an inner ProofSizeProvider that is used to get the actual encoded size estimations. Each estimation is recorded in the order it was observed.
