This avoids the name clash with `rustc_serialize::Encoder` (a trait), and allows lots qualifiers to be removed and imports to be simplified (e.g. fewer `as` imports). (This was previously merged as commit 5 in #94732 and then was reverted in #97905 because of a perf regression caused by commit 4 in #94732.) |

The rustc_ast
crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).
For more information about how these things work in rustc, see the rustc dev guide:
