//! hir makes heavy use of ids: integer (u32) handlers to various things. You
|
|
//! can think of id as a pointer (but without a lifetime) or a file descriptor
|
|
//! (but for hir objects).
|
|
//!
|
|
//! This module defines a bunch of ids we are using. The most important ones are
|
|
//! probably `HirFileId` and `DefId`.
