Crate slice[−][src]
Create slices of IO objects - std::io::Read
and std::io::Write
.
If you have a file (or any other object), you can create a slice (or view) into some subset of it.
IoSlice
impls both std::io::Read
and std::io::Write
when the source implements them (and only one if the source
only implements one).
example usage.
use { std::fs::File, slice::IoSlice }; let source = File::open("/home/annie/data.png")?; let start = 10; let length = 1000; // create a slice into `home/annie/data.png`, consisting of bytes [10 .. 10 + 1000] // of that file. // // `slice` impls both `std::io::Read` and `std::io::Write` because `source` // does too. let slice = IoSlice::new(source, start, length); // use like any other `std::io::Read` or `std::io::Write`: // // slice.read_to_string(...)?; // slice.read_exact(...)?; // slice.write_all(...)?; // // writeln!(slice, "hello {}", name)?; //
