Trait lightning::chain::chaininterface::FeeEstimator [−][src]
pub trait FeeEstimator { fn get_est_sat_per_1000_weight(
&self,
confirmation_target: ConfirmationTarget
) -> u32; }
Expand description
A trait which should be implemented to provide feerate information on a number of time horizons.
Note that all of the functions implemented here must be reentrant-safe (obviously - they’re called from inside the library in response to chain events, P2P events, or timer events).
Required methods
fn get_est_sat_per_1000_weight(
&self,
confirmation_target: ConfirmationTarget
) -> u32
[src]
fn get_est_sat_per_1000_weight(
&self,
confirmation_target: ConfirmationTarget
) -> u32
[src]Gets estimated satoshis of fee required per 1000 Weight-Units.
Must be no smaller than 253 (ie 1 satoshi-per-byte rounded up to ensure later round-downs don’t put us below 1 satoshi-per-byte).
This translates to:
- satoshis-per-byte * 250
- ceil(satoshis-per-kbyte / 4)
