hygiene | Machinery for hygienic macros, inspired by the |
source_map | The |
symbol | An "interner" is a data structure that associates values with usize tags and allows bidirectional lookup; i.e., given a value, one can easily find the type, and vice versa. |
Structs
BytePos | A byte offset. Keep this small (currently 32-bits), as AST contains a lot of them. |
CachingSourceMapView | |
CharPos | A character offset. Because of multibyte UTF-8 characters, a byte offset
is not equivalent to a character offset. The |

InnerSpan | Range inside of a |
LineInfo | |
Loc | A source code location used for error reporting. |
MalformedSourceMapPositions | |
MultiByteChar | Identifies an offset of a multi-byte character in a |
MultiSpan | A collection of spans. Spans have two orthogonal attributes: |
NormalizedPos | Identifies an offset of a character that was normalized away from |
OffsetOverflowError | |
SourceFile | A single source in the |
SourceFileAndBytePos | |

Span | A compressed span. |
SpanData | Spans represent a region of code, used for error reporting. Positions in spans
are absolute positions from the beginning of the source_map, not positions
relative to |
SpanLabel |
Enums
ExternalSource | The state of the lazy external source loading mechanism of a |
FileName | Differentiates between real files and common virtual files. |
NonNarrowChar | Identifies an offset of a non-narrow character in a |

Constants
DUMMY_SP | Dummy span, both position and length are zero, syntax context is zero as well. |
