### Important traits for Box<I>

`impl<I: Iterator + ?Sized> Iterator for Box<I> type Item = I::Item;`

    pub unsafe fn from_boxed_utf8_unchecked(v: Box<[u8]>) -> Box<str>

Converts a boxed slice of bytes to a boxed string slice without checking that the string contains valid UTF-8.

# Examples

Basic usage:

    let smile_utf8 = Box::new([226, 152, 186]);

## 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`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
