Helper trait to generalize comparisons (see `eq_named_lists`).

A context for a GraphQL document which holds an arena allocator. For the duration of parsing, storing, validating, traversing, and printing an AST it

An enum of identifiers representing AST nodes. This enum can be printed using the [`fmt::Display`] trait. When parsing this enum is used to indicate

This structure implements the `Visitor` trait and runs two child Visitors in parallel, executing and calling callbacks on them both. During traversal

Trait for folding a GraphQL Document AST Node by traversing an operation instead of the entire AST tree. This method alters the traversal of the folde

Trait for a folder that carries methods that are called as callback while AST nodes implementing the folder pattern are traversed and edited. A Folde
