Trait io_lifetimes::FromFilelike

fn from_filelike(owned: OwnedFilelike) -> Self;
fn from_into_filelike<Owned: IntoFilelike>(owned: Owned) -> Self;
}
Expand description
A portable trait to express the ability to construct an object from a filelike object.
This is a portability abstraction over Unix-like FromFd
and Windows’
FromHandle
. It also provides the from_into_filelike
convenience
function providing simplified from+into conversions.
Required methods
fn from_filelike(owned: OwnedFilelike) -> Self
fn from_filelike(owned: OwnedFilelike) -> Self
Constructs a new instance of Self
from the given filelike object.
Example
use std::fs::File;
use io_lifetimes::{FromFilelike, IntoFilelike, OwnedFilelike};
let f = File::open("foo.txt")?;
let owned_filelike: OwnedFilelike = f.into_filelike();
let f = File::from_filelike(owned_filelike);
fn from_into_filelike<Owned: IntoFilelike>(owned: Owned) -> Self
fn from_into_filelike<Owned: IntoFilelike>(owned: Owned) -> Self
Constructs a new instance of Self
from the given filelike object
converted from into_owned
.
Example
use std::fs::File;
use io_lifetimes::{FromFilelike, IntoFilelike};
let f = File::open("foo.txt")?;
let f = File::from_into_filelike(f);
