# Trait std::ops::RangeBounds [−] [src]

    pub trait RangeBounds<T> where
        T: ?Sized, {
        fn start(&self) -> Bound<&T>;
        fn end(&self) -> Bound<&T>;
    }

🔬 This is a nightly-only experimental API. (`collections_range` #30877)

might be replaced with `Into<_>` and a type containing two `Bound` values

`RangeBounds` is implemented by Rust's built-in range types, produced by range syntax like `..`, `a..`, `..b` or `c..d`.

## Required Methods

### `fn start(&self) -> Bound<&T>`

🔬 This is a nightly-only experimental API. (`collections_range` #30877)

might be replaced with `Into<_>` and a type containing two `Bound` values

Start index bound.

Returns the start value as a `Bound`.

# Examples

    #![feature(collections_range)]

    use std::ops::Bound::*;
    use std::ops::RangeBounds;

    assert_eq!((..10).start(), Unbounded);
    assert_eq!((3..10).start(), Included(&3));Run

### `fn end(&self) -> Bound<&T>`

🔬 This is a nightly-only experimental API. (`collections_range` #30877)

might be replaced with `Into<_>` and a type containing two `Bound` values

End index bound.

Returns the end value as a `Bound`.

# Examples

    #![feature(collections_range)]

    use std::ops::Bound::*;
    use std::ops::RangeBounds;

    assert_eq!((3..).end(), Unbounded);
    assert_eq!((3..10).end(), Excluded(&10));Run

## 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`)
