§docs: &'static str

Link to the unstable documentation.

§get: fn(_: &Features) -> bool

Implementations§

source§

impl Feature

source

pub const fn test_dummy_stable() -> &'static Feature

A dummy feature that doesn’t actually gate anything, but it’s used in testing to ensure that we can enable stable features.

See https://doc.rust-lang.org/nightly/cargo/.

source

pub const fn test_dummy_unstable() -> &'static Feature

A dummy feature that gates the usage of the im-a-teapot manifest entry. This is basically just intended for tests.

See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html.

source

pub const fn alternative_registries() -> &'static Feature

See https://doc.rust-lang.org/nightly/cargo/reference/registries.html.

source

pub const fn edition() -> &'static Feature

source

pub const fn rename_dependency() -> &'static Feature

source

See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#open-namespaces.

source

pub const fn path_bases() -> &'static Feature
