Expand description

Experimental new types and traits to replace the Raw family of types and traits.

This API has much conceptual similarity with the Raw API, but introduces explicit concepts of ownership and borrowing:

`Raw` API	This experimental API
`Raw*`	`Borrowed` and `Owned`
`AsRaw*`	`As*`
`IntoRaw*`	`Into*`
`FromRaw*`	`From*`

This gives it several advantages:

Less unsafe in user code!
Easier to understand ownership.
It avoids the inconsistency where AsRawFd and IntoRawFd return RawFd values that users ought to be able to trust, but aren’t unsafe, so it’s possible to fail to uphold this trust in purely safe Rust.
It enables a number of safe and portable convenience features, such as safe typed views and from+into conversions.

Modules

Typed views using temporary objects.

Structs

A borrowed file descriptor.

Traits

A trait to borrow the file descriptor from an underlying object.

A portable trait to borrow a reference from an underlying filelike object.

A trait to express the ability to construct an object from a file descriptor.

A portable trait to express the ability to construct an object from a filelike object.

A portable trait to express the ability to construct an object from a socketlike object.

A trait to express the ability to consume an object and acquire ownership of its file descriptor.

A portable trait to express the ability to consume an object and acquire ownership of its filelike object.
