Struct Dictionary 

pub struct Dictionary { /* private fields */ }

Implementations

impl Dictionary

pub fn get<K: AsRef<str>>(&self, key: K) -> Option<&str>

Try to find a value in the dictionary.

This function uses case-insensitive matching of the entire key string to find a value. If you want to customize the way FFmpeg searches for the key, see get_with_flags.

impl Dictionary

pub fn get_with_flags<K: AsRef<str>>( &self, key: K, flags: Flags, ) -> Option<&str>

Try to find a value in the dictionary, using custom search flags.

See Flags to see how each flag works. Using Flags::DONT_STRDUP_KEY is heavily discouraged unless you know what you are doing.

impl Dictionary

pub fn len(&self) -> usize

Returns the number of entries in the dictionary.

impl Dictionary

pub fn is_empty(&self) -> bool

Returns true if the dictionary is empty.

impl Dictionary

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

Creates an iterator over all key-value pairs in the dictionary.

impl Dictionary

pub fn set<K, V>(&mut self, key: K, value: V)

where K: AsRef<str>, V: AsRef<str>,

Set a value for the given key.

This function will overwrite any value that already exists for the given key. If you want to customize the way FFmpeg inserts the new value, see set_with_flags.

impl Dictionary

pub fn set_with_flags<K, V>(&mut self, key: K, value: V, flags: Flags)

where K: AsRef<str>, V: AsRef<str>,

Set a value for the given key, using custom flags.

See Flags to see how each flag works. Using Flags::DONT_STRDUP_KEY or Flags::DONT_STRDUP_VAL is heavily discouraged unless you know what you are doing.

impl Dictionary

pub fn unset<K: AsRef<str>>(&mut self, key: K)

Remove a value from the dictionary for the given key.

If you want to customize the way FFmpeg searches for the key, see unset_with_flags.

impl Dictionary

pub fn unset_with_flags<K: AsRef<str>>(&mut self, key: K, flags: Flags)

Remove a value from the dictionary for the given key, using custom flags.

See Flags to see how each flag works. Using Flags::DONT_STRDUP_KEY or Flags::DONT_STRDUP_VAL is heavily discouraged unless you know what you are doing.

Trait Implementations

impl AsMutPtr<*mut AVDictionary> for Dictionary

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

Returns a *mut raw pointer to the underlying FFmpeg type.

impl AsPtr<AVDictionary> for Dictionary

fn as_ptr(&self) -> *const AVDictionary

impl Clone for Dictionary

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Dictionary

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

impl Default for Dictionary

fn default() -> Self

Returns the “default value” for a type.

impl Drop for Dictionary

fn drop(&mut self)

Executes the destructor for this type.

impl<S, U> FromIterator<(S, U)> for Dictionary

where S: AsRef<str>, U: AsRef<str>,

fn from_iter<T: IntoIterator<Item = (S, U)>>(iter: T) -> Self

Creates a value from an iterator.
