std.encoding

Encoding and decoding utilities - base64, hex, and UTF-8 operations.

The module re-exports three sub-modules:

• std.encoding.base64 - Base64 encoding/decoding (standard and URL-safe)
• std.encoding.hex - Hexadecimal encoding/decoding (upper and lower case)
• std.encoding.utf8 - UTF-8 validation

All operations are backed by the Rust runtime.

Sub-modules

base64

encode(data: String) -> String

Encodes data to standard Base64.

encode_url_safe(data: String) -> String

Encodes data to URL-safe Base64 (uses - and _ instead of + and /).

decode(data: String) -> String

Decodes a Base64-encoded string back to the original data.

load std.encoding.base64

let enc = base64.encode("hello world")
let dec = base64.decode(enc)

hex

encode(data: String) -> String

Encodes data to a lowercase hexadecimal string.

encode_upper(data: String) -> String

Encodes data to an uppercase hexadecimal string.

decode(hex: String) -> String

Decodes a hexadecimal string back to the original data.

load std.encoding.hex

let enc = hex.encode("hello")
let upp = hex.encode_upper("hello")
let dec = hex.decode(enc)

utf8

validate(data: String) -> Bool

Returns true if data is valid UTF-8.

len(s: String) -> Int

Returns the byte length of string s.

load std.encoding.utf8

let ok = utf8.validate("hello")
let n = utf8.len("hello")
