Creates a new I/O error from a known kind of error and a string literal.

Unix-specific extensions to general I/O primitives.

Copies the entire contents of a reader into a writer.

A locked reference to the `Stdin` handle.

A future represents an asynchronous computation obtained by use of `async`.

Bind a value to a variable.

A UTF-8–encoded, growable string.

Objects that have a notion of successor and predecessor operations.

The right shift operator `>>`. Note that because this trait is implemented for all integer types with multiple right-hand-side types, Rust’s type checker has special handling for `_ >> _`, setting the result type for integer operations to the type of the left-hand-side operand. This means that though `a >> b` and `a.shr(b)` are one and the same from an evaluation standpoint, they are different when it comes to type inference.

Required trait for constants used in pattern matches.
