[−][src]Struct libwebp::boxed::WebpBox

pub struct WebpBox<T: ?Sized> { /* fields omitted */ }

A safe RAII wrapper for WebPFree.

WebpBox is much like Box, except what function is used for freeing.

Example

The main usecase is as a return value from libwebp.

use libwebp::WebPEncodeRGBA;

let buf: &[u8];
// This variable has the type of `WebpBox<[u8]>`.
let data = WebPEncodeRGBA(buf, 2, 2, 8, 75.0).unwrap();

Methods

impl<T: ?Sized> WebpBox<T>[src]

pub unsafe fn from_raw(raw: *mut T) -> WebpBox<T>[src]

Creates WebpBox from a raw pointer.

Safety

  • raw must be non-null.
  • raw must be well-aligned.
  • The pointee must be valid as T.
  • The pointee must be exclusively accessible.
  • raw must be freeable via WebPFree.

pub fn into_raw(b: WebpBox<T>) -> *mut T[src]

Turns WebpBox into a raw pointer without freeing anything.
