Struct bdk_wallet::coin_selection::OldestFirstCoinSelection

pub struct OldestFirstCoinSelection;

OldestFirstCoinSelection always picks the utxo with the smallest blockheight to add to the selected coins next

This coin selection algorithm sorts the available UTXOs by blockheight and then picks them starting from the oldest ones until the required amount is reached.
