Rux Standard Library

The standard library for the Rux programming language.

Modules

Std

Core types and utilities available by default.

Type / Function	Description
String	Heap-allocated UTF-8 string with From, +, Data, Length
StringBuilder	Growable buffer with New, Append (char, slice, String), ToString
Display	Interface requiring ToString() -> String
Format(fmt, args...)	String interpolation using {} placeholders
Exit(code)	Terminate the process with an exit code

Std::Math

Mathematical constants and functions.

Symbol	Description
Pi, E	Mathematical constants (float64)
Sin, Cos, Tan	Trigonometric functions (float32 / float64)
Sqrt, Pow	Square root and exponentiation
Abs, Floor, Ceil, Round	Rounding and absolute value

Std::Memory

Low-level heap memory management backed by the Windows process heap.

Function	Description
Alloc(size)	Allocate size bytes
Realloc(ptr, size)	Resize an existing allocation
Free(ptr)	Release an allocation
Copy(dest, src, len)	Copy len bytes
Zero(ptr, size)	Zero-fill size bytes
Set(ptr, size, value)	Fill size bytes with value

Std::Io

Console I/O.

Function	Description
Print(str: String)	Write a string to stdout (UTF-8 → UTF-16 via WriteConsoleW)
Print(fmt, args...)	Format and print (work in progress)

Display implementations

The following built-in types implement the Display interface and can be passed to Format / Print:

• bool8 — renders as "true" or "false"
• int64 — decimal integer rendering
• float64 — decimal with 6 fractional digits, plus "NaN", "Inf", "-Inf"

Usage

import Std::{ String, Format };
import Std::Io::Print;

func Main() {
    let msg = Format("Hello, {}!", "world");
    Print(msg);
}

Requirements

• Windows (memory and I/O modules depend on the Windows package)
