Structs

BottomUpBuilder	A builder for creating parse trees by a bottom-up walk over the tree nodes.
ParseTree	The parse tree for a single source file.
PtNode
PtNodeId
Symbol	A type of a syntactic construct, including both leaf tokens and composite nodes, like "a comma" or "a function".
TextRange	A range in the text, represented as a pair of `TextUnit`s.
TextUnit	An offset into text. Offset is represented as `u32` storing number of utf8-bytes, but most of the clients should treat it like opaque measure.
Token	A token of source code.
TopDownBuilder	A builder for creating parse trees by a top-down walk over the tree nodes. Each `start_internal` call must be paired with a `finish_internal` call. Nodes created within a pair of `start_internal` / `finish_internal` calls become children of the internal node.
