# Enum oxipng::png::Headers [−] [src]

    pub enum Headers {
        None,
        Some(Vec<String>),
        Safe,
        All,
    }

Options to use for performing operations on headers (such as stripping)

## Variants

`None` | None |
`Some` | Some, with a list of 4-character chunk codes |
`Safe` | Headers that won't affect rendering (all but cHRM, gAMA, iCCP, sBIT, sRGB, bKGD, hIST, pHYs, sPLT) |
`All` | All non-critical headers |

## 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`)
