Std api

Every public declaration of the packaged library, with its bounds, the comment above it and the effect row the checker infers, one page per module. library.md is the guide to what each is for.

module	what it holds
std.arena	A generational arena: values live in one owned array and are named by a copyable Handle instead of a borrow, which is how CAIRN expresses graphs and cycles.
std.core	The vocabulary every other module shares, and the limits of each integer type.
std.derived	Implementations written once for any record whose fields already have them: derive eq for Point;, derive ord for Point;, derive hash for Point;.
std.draw	Drawing into an Image on the CPU: filled rectangles, lines, filled circles, source-over blending, blits of one image onto another, text in a built-in 8 by 13 bitmap font, and the layout record and frame capture that let a person or an agent see what a program drew.
std.env	The program's arguments and environment, as it was started.
std.fmt	Text built into a byte Vec: each call appends to out, so a line is a run of calls and one write.
std.fs	Files by path.
std.image	RGBA images held in one owned array of pixels, and the files that hold them: PNG, which every viewer opens, and the plain PPM.
std.io	Files and standard streams.
std.map	An open-addressed hash table with linear probing and tombstones.
std.math	The C math library's functions on f64.
std.mem	Element-wise bulk operations on host views.
std.net	Blocking TCP over the C library.
std.sort	In-place ordering.
std.sys	The C library, declared exactly once: every other module borrows these names instead of redeclaring them, because an extern's C symbol is its CAIRN name and two declarations of one symbol collide in the emitted program.
std.text	Numbers to bytes and back, the ASCII class of a byte, and the searching a line protocol needs.
std.time	Clocks and waiting.
std.vec	A growable owner.
std.wire
std.zlib	The system zlib through its one-shot C interface: the zlib stream of a whole view, and the CRC-32 and Adler-32 checksums that PNG files and zlib streams carry.
