util

Documentation

Overview

Package util contains some special useful functions that are provided by compiler and VM.

Index

• func Equals(a, b interface{}) bool
• func FromAddress(address string) []byte
• func Remove(sliceOrMap, key interface{})

Functions

func Equals

func Equals(a, b interface{}) bool

Equals compares a with b and will return true when a and b are equal. It's implemented as an EQUAL VM opcode, so the rules of comparison are those of EQUAL.

func FromAddress

func FromAddress(address string) []byte

FromAddress is an utility function that converts a Neo address to its hash (160 bit BE value in a 20 byte slice). It can only be used for strings known at compilation time, because the convertion is actually being done by the compiler.

func Remove

func Remove(sliceOrMap, key interface{})

Remove removes item with the specified key from slice or map. For maps it is similar to `delete`. For slices it performs mutable update as if slice was provided by pointer.
