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?

Token Streams

A TokenStream is an abstract sequence of tokens, organized into TokenTrees. The goal is for procedural macros to work with TokenStreams and TokenTrees instead of a representation of the abstract syntax tree. Today's TokenTrees can still contain AST via Token::Interpolated for back-compat.
