Feature Bits

Provided Methods

fn requirements(&self) -> Self

Returns the feature that this feature requires.

If self is a single feature and multiple features are returned, self requires only one of them.

Examples

use virtio::FeatureBits;

assert_eq!(
    virtio::net::F::GUEST_TSO4.requirements(),
    virtio::net::F::GUEST_CSUM
);
assert_eq!(
    virtio::net::F::GUEST_ECN.requirements(),
    virtio::net::F::GUEST_TSO4 | virtio::net::F::GUEST_TSO6
);

fn requirements_satisfied(&self) -> bool

Returns true if all internal feature requirements are satisfied.

Examples

use virtio::FeatureBits;

assert!((virtio::net::F::GUEST_TSO4 | virtio::net::F::GUEST_CSUM).requirements_satisfied());
assert!(
    (virtio::net::F::GUEST_ECN | virtio::net::F::GUEST_TSO4 | virtio::net::F::GUEST_CSUM)
        .requirements_satisfied()
);

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.
