Mmap

✓ use memmap2::Mmap;

Memory-map a file and read its contents.

use memmap2::Mmap; use std::fs::File; fn main() -> std::io::Result<()> { let file = File::open("example.txt")?; let mmap = unsafe { Mmap::map(&file)? }; println!("{:?}", &mmap[..10]); Ok(()) }

Debug

Known issues

gotchaMmap::map is unsafe because it can cause undefined behavior if the underlying file is mutated concurrently.

fix

Ensure the file is not modified while the mapping exists, or use `Mmap::map_readonly` for read-only access.

affects: >=0.1.0
