Module syntex_syntax::codemap
[−]
[src]
The CodeMap tracks all the source code used within a single crate, mapping
from integer byte positions to the original source code location. Each bit
of source parsed during crate parsing (typically files, in-memory strings,
or various bits of macro expansion) cover a continuous range of bytes in the
CodeMap and are represented by FileMaps. Byte positions are stored in
spans and used pervasively in the compiler. They are absolute positions
within the CodeMap, which upon request can be converted to line and column
information, source code snippets, etc.
