Module rustc_span::analyze_source_file
source ยท Functionsยง
- Finds all newlines, multi-byte characters, and non-narrow characters in a SourceFile.
- Checks 16 byte chunks of text at a time. If the chunk contains something other than printable ASCII characters and newlines, the function falls back to the generic implementation. Otherwise it uses SSE2 intrinsics to quickly find all newlines.
