lib.rs	A cross-platform Rust API for memory mapped buffers. The core functionality is provided by either [`Mmap`] or [`MmapMut`], which correspond to mapping a [`File`] to a [`&[u8]`](https://doc.rust-lang.org/std/primitive.slice.html) or [`&mut [u8]`](https://doc.rust-lang.org/std/primitive.slice.html) respectively. Both function by dereferencing to a slice, allowing the [`Mmap`]/[`MmapMut`] to be used in the same way you would the equivalent slice types. [`File`]: std::fs::File # Examples For simple cases [`Mmap`] can be used directly: ``` use std::fs::File; use std::io::Read; use memmap2::Mmap; # fn main() -> std::io::Result<()> { let mut file = File::open("LICENSE-APACHE")?; let mut contents = Vec::new(); file.read_to_end(&mut contents)?; let mmap = unsafe { Mmap::map(&file)? }; assert_eq!(&contents[..], &mmap[..]); # Ok(()) # } ``` However for cases which require configuration of the mapping, then you can use [`MmapOptions`] in order to further configure a mapping before you create it.	69945	97 %
