When building up our path cache, we don't plaster over a path which was previously inserted if we're inserting a non-public-item thing. Closes #11678

//! Rustdoc's HTML Rendering module
|
|
//!
|
|
//! This modules contains the bulk of the logic necessary for rendering a
|
|
//! rustdoc `clean::Crate` instance to a set of static HTML pages. This
|
|
//! rendering process is largely driven by the `format!` syntax extension to
|
|
//! perform all I/O into files and streams.
|
|
//!
|
|
//! The rendering process is largely driven by the `Context` and `Cache`
|
|
//! structures. The cache is pre-populated by crawling the crate in question,
|
|
//! and then it is shared among the various rendering tasks. The cache is meant
|
|
//! to be a fairly large structure not implementing `Clone` (because it's shared
|
|
//! among tasks). The context, however, should be a lightweight structure. This
|
|
//! is cloned per-task and contains information about what is currently being
|
|
//! rendered.
|
|
//!
|
|
//! In order to speed up rendering (mostly because of markdown rendering), the
|
|
//! rendering process has been parallelized. This parallelization is only
|
|
//! exposed through the `crate` method on the context, and then also from the
|
|
//! fact that the shared cache is stored in TLS (and must be accessed as such).
|
|
//!
|
|
//! In addition to rendering the crate itself, this module is also responsible
|
|
//! for creating the corresponding search index and source file renderings.
|
|
//! These tasks are not parallelized (they haven't been a bottleneck yet), and
|
|
//! both occur before the crate is rendered.
