结构体 Mut 

pub struct Mut<'a> { /* 私有字段 */ }

实现

impl<'a> Ref<'a>

pub unsafe fn wrap(ptr: *mut AVDictionary) -> Self

pub unsafe fn as_mut_ptr(&self) -> *mut AVDictionary

impl<'a> Ref<'a>

pub fn set(&mut self, key: &str, value: &str)

Methods from Deref<Target = Ref<'a>>

pub unsafe fn as_ptr(&self) -> *const AVDictionary

pub fn get(&'a self, key: &str) -> Option<&'a str>

pub fn iter(&self) -> Iter<'_>

pub fn to_owned<'b>(&self) -> Owned<'b>

trait 实现

impl<'a> Debug for Ref<'a>

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

使用给定的格式化器格式化该值。 阅读更多

impl<'a> Deref for Ref<'a>

type Target = Ref<'a>

解引用之后得到的类型。

fn deref(&self) -> &Self::Target

解引用该值。
