Trait Clircle

pub trait Clircle:
    Eq
    + TryFrom<Stdio>
    + TryFrom<File> {
    // Required method
    fn into_inner(self) -> Option<File>;

    // Provided methods
    fn surely_conflicts_with(&self, _other: &Self) -> bool { ... }
    fn stdin() -> Option<Self> { ... }
    fn stdout() -> Option<Self> { ... }
    fn stderr() -> Option<Self> { ... }
}

The Clircle trait describes the public interface of the crate. It contains all the platform-independent functionality. Additionally, an implementation of Eq is required, that gives a simple way to check for conflicts, if using the more elaborate surely_conflicts_with method is not wanted. This trait is implemented for the structs UnixIdentifier and WindowsIdentifier.

Required Methods

fn into_inner(self) -> Option<File>

Returns the File that was used for From<File>. If the instance was created otherwise, this may also return None.

Provided Methods

fn surely_conflicts_with(&self, _other: &Self) -> bool

Checks whether the two values will without doubt conflict. By default, this always returns false, but implementors can override this method. Currently, only the Unix implementation overrides surely_conflicts_with.

fn stdin() -> Option<Self>

Shorthand for try_from(Stdio::Stdin).

fn stdout() -> Option<Self>

Shorthand for try_from(Stdio::Stdout).

fn stderr() -> Option<Self>

Shorthand for try_from(Stdio::Stderr).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
