Module syntax::fold

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

A Folder represents an AST->AST fold; it accepts an AST piece, and returns a piece of the same type. So, for instance, macro expansion is a Folder that walks over an AST and produces another AST.

Note: using a Folder (other than the MacroExpander Folder) on an AST before macro expansion is probably a bad idea. For instance, a folder renaming item names in a module will miss all of those that are created by the expansion of a macro.
