var OsmoUtilsExtraAccountTypes map[reflect.Type]struct{}

OsmoUtilsExtraAccountTypes is a map of extra account types that can be overridden. This is defined as a global variable so it can be modified in the chain's app.go and used here without having to import the chain. Specifically, this is used for compatibility with Osmosis' Cosmos SDK fork

Functions

func AddDecCoinArrays added in v0.0.5 

func AddDecCoinArrays(decCoinsArrayA []sdk.DecCoins, decCoinsArrayB []sdk.DecCoins) ([]sdk.DecCoins, error)

AddDecCoinArrays adds the contents of the second param from the first (decCoinsArrayA + decCoinsArrayB) Note that this takes in two _arrays_ of DecCoins, meaning that each term itself is of type DecCoins (i.e. an array of DecCoin).

func ApplyFuncIfNoError 

func ApplyFuncIfNoError(ctx sdk.Context, f func(ctx sdk.Context) error) (err error)

This function lets you run the function f, but if there's an error or panic drop the state machine change and log the error. If there is no error, proceeds as normal (but with some slowdown due to SDK store weirdness) Try to avoid usage of iterators in f.

If its an out of gas panic, this function will also panic like in normal tx execution flow. This is still safe for beginblock / endblock code though, as they do not have out of gas panics.

func CWCoinFromSDKCoin added in v0.0.8 

func CWCoinFromSDKCoin(in sdk.Coin) wasmvmtypes.Coin

Convert sdk.Coin to wasmvmtypes.Coin

func CWCoinsFromSDKCoins added in v0.0.8

func CanCreateModuleAccountAtAddr 

func CanCreateModuleAccountAtAddr(ctx sdk.Context, ak AccountKeeper, addr sdk.AccAddress) error

CanCreateModuleAccountAtAddr tells us if we can safely make a module account at a given address. By collision resistance of the address (given API safe construction), the only way for an account to be already be at this address is if its claimed by the same pre-image from the correct module, or some SDK command breaks assumptions and creates an account at designated address. This function checks if there is an account at that address, and runs some safety checks to be extra-sure its not a user account (e.g. non-zero sequence, pubkey, of fore-seen account types). If there is no account, or if we believe its not a user-spendable account, we allow module account creation at the address. else, we do not.

TODO: This is generally from an SDK design flaw code based off wasmd code: https://github.com/CosmWasm/wasmd/pull/996 Its _mandatory_ that the caller do the API safe construction to generate a module account addr, namely, address.Module(ModuleName, {key})

func CollapseDecCoinsArray added in v0.0.5

func DisjointArrays added in v0.0.8 

func DisjointArrays(a, b []uint64) []uint64

DifferenceBetweenUint64Arrays takes two slices of uint64, 'a' and 'b', as input. It returns a new slice containing the elements that are unique to either 'a' or 'b'. The function uses two maps for efficient lookup of elements.

Example: a := []uint64{1, 2, 3, 4, 5} b := []uint64{4, 5, 6, 7, 8} result := DisjointArrays(a, b) result will be []uint64{1, 2, 3, 6, 7, 8}
