Trait io_lifetimes::FromFilelike [−][src]
pub trait FromFilelike: FromHandle { 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
[src]
fn from_filelike(owned: OwnedFilelike) -> Self
[src]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
[src]
fn from_into_filelike<Owned: IntoFilelike>(owned: Owned) -> Self
[src]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);
