# Enum std::collections::Bound [−] [src]

    pub enum Bound<T> {
        Included(T),
        Excluded(T),
        Unbounded,
    }

Unstable (`collections_bound` #27787)

An endpoint of a range of keys.

## Variants

`Included` | Unstable (`collections_bound` #27787) An inclusive bound. |
`Excluded` | Unstable (`collections_bound` #27787) An exclusive bound. |
`Unbounded` | Unstable (`collections_bound` #27787) An infinite endpoint. Indicates that there is no bound in this direction. |

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
