Hex Package

The Flux Hex Package provides functions that perform hexadecimal conversion of int, uint or bytes values to/from string values.

hex.string

The hex.string() function converts a single value to a string. It is like a standard string() function, but it encodes int, uint and bytes to hexadecimal lowercase characters.

Example:

import "contrib/bonitoo-io/hex"

a = hex.string(v: 12)
// a is "c"
b = hex.string(v: bytes(v: "hi"))
// b is "6869"

hex.int

The hex.int() function converts a hexadecimal string representation of a number value to an integer. An input value can be optionally prefixed by 0x.

Example:

import "contrib/bonitoo-io/hex"

a = hex.int(v: "c")
// a is 12
b = hex.int(v: "-d")
// b is -13
c = hex.int(v: "0xe")
// c is 14
c = hex.int(v: "-0xF")
// d is -15

hex.uint

The hex.uint() function converts a hexadecimal string representation of a number to an unsigned integer. An input value can be optionally prefixed by 0x.

Example:

import "contrib/bonitoo-io/hex"

a = hex.uint(v: "C")
// a is uint(12)
b = hex.int(v: "0xd")
// b is uint(13)

hex.bytes

The hex.bytes() function decodes a string of hexadecimal characters into a flux bytes value.

Example:

import "contrib/bonitoo-io/hex"

a = hex.bytes(v: "6869")
// a is bytes("hi")
