Overview

Package coinsort provides helpers to sort a slice of banker.Coins using the classic sort.Sort API (without relying on sort.Slice).

Usage examples:

Example
1coins := banker.GetCoins("g1....")
2
3// Ascending by balance
4coinsort.SortByBalance(coins)
5
6// Custom order – largest balance first
7coinsort.SortBy(coins, func(a, b chain.Coin) bool {
8    return a.Amount > b.Amount // descending
9})

Note: when getting banker.Coins from the banker, it's sorted by denom by default.

Functions 2

func SortBy 

1func SortBy(c chain.Coins, less LessFunc)
source

SortBy sorts c in place using the provided LessFunc.

Example – descending by Amount:

Example
1coinsort.SortBy(coins, func(a, b banker.Coin) bool {
2    return a.Amount > b.Amount
3})

func SortByBalance 

1func SortByBalance(c chain.Coins)
source

SortByBalance sorts c in ascending order by Amount.

Example
1coinsort.SortByBalance(myCoins)
