Variants§

§

Single

One import, e.g., use foo::bar or use foo::bar as baz. Also produced for each element of a list use, e.g. use foo::{a, b} lowers to use foo::a; use foo::b;.

§

Glob

Glob import, e.g., use foo::*.

§

ListStem

Degenerate list import, e.g., use foo::{a, b} produces an additional use foo::{} for performing checks such as unstable feature gating. May be removed in the future.

Trait Implementations§

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
