# [−][src]Enum rusttype::SharedBytes

    pub enum SharedBytes<'a> {
        ByRef(&'a [u8]),
        ByArc(Arc<[u8]>),
    }

`SharedBytes` handles the lifetime of font data used in RustType. The data is either a shared reference to externally owned data, or managed by reference counting. `SharedBytes` can be conveniently used with `From` and `Into`, and dereferences to the contained bytes.

# Lifetime

The lifetime reflects the font data lifetime. `SharedBytes<'static>` covers most cases ie both dynamically loaded owned data and for referenced compile time font data.

## Variants

`ByRef(&'a [u8])`
`ByArc(Arc<[u8]>)`

## 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`)
