Every crate and every public function

The lessons of this course each take one family of algorithms and go deep. This page does the opposite: it lists everything, so that a name met in a tool result or an error message can be traced back to the crate and module it came from.

It is generated by scripts/sync-ix-api-map.mjs from a local IX checkout, with one git grep over the pinned commit — never edited by hand. Run npm run sync:ix-api-map to rebuild it after re-pinning.

Caution

What is counted. Every pub fn, pub struct, pub enum, pub trait, pub const and pub type declared under crates/*/src/. That is what the source says, not what a caller can reach: an item declared pub inside a private module is listed here and is invisible from outside the crate. Trait methods and items inside impl blocks are included when they are written pub. Anything behind a Cargo feature is listed whether or not the feature is on.
