Crate bitcoin_coin_selection 

Rust Bitcoin coin selection library.

Efficient algorithms for choosing an optimal UTXO set.

Modules

errors

Possible returned error types if no match is found.

Structs

WeightedUtxo

Represents the spendable conditions of a UTXO.

Functions

branch_and_bound

Performs a deterministic depth first branch and bound search for a changeless solution.

select_coinsrand

Attempt a match with branch_and_bound falling back to single_random_draw.

single_random_drawrand

Randomize the input set and select coins until the target is reached. If the maximum weight is exceeded, then the least valuable inputs are removed from the selection using weight as a tie breaker. In so doing, minimize the number of UTXOs included in the result by preferring UTXOs with higher value.
