Module io

Enums§

FileData: Holds file data — either zero-copy mmap or an owned Vec. Dereferences to &[u8] for transparent use.

Functions§

file_size: Get file size without reading it (for byte-count-only optimization).
read_file: Read a file with zero-copy mmap for large files or read() for small files. Opens once with O_NOATIME, uses fstat for metadata to save a syscall.
read_stdin: Read all bytes from stdin into a Vec.
