# Standard Library
## Strings
#### `pub struct String`
Editable string value that can be printed and extended
Has the following binops defined:
- `String` + `*char` = `String`
- `String` + `u64` = `String`
#### `pub fn print(message: String)`
Prints given `message` to the standard output
#### `pub fn new_string() -> String`
Returns a new empty `String`-object, which must later be manually freed.
#### `pub fn from_str(string: *char) -> String`
Creates a new `String`-object containing initially data from the given string-literal which must be later freed.
#### `pub fn set_char(string: &mut String, c: char, position: u64)`
Edits given `string` by setting the character at index `position` to be `c`.
#### `pub fn add_num_to_string(string: &mut String, num: u64)`
Formats the given number into the end of the string.
#### `pub fn concat_strings(destination: &mut String, source: String)`
Concatenates `source` to the end of `destination`.
## General
#### `pub fn allocate(size: u64) -> *u8`
Unsafely allocates `size` bytes of memory from the stack, and returns a pointer to it, which must be manually freed.
## Maths
#### `pub fn clamp(min: f32, max: f32, value: f32) -> f32`
Returns `value` as clamped between `min` and `max`. Equivalent to `max(min(value, max), min)`
#### `pub fn abs(value: f32) -> f32`
Returns the absolute value of `value`.
