Struct MediaPermissions

pub struct MediaPermissions<'a> { /* private fields */ }

Writer for an media permissions dictionary.

This struct is created by MediaClip::permissions.

Implementations

impl<'a> MediaPermissions<'a>

pub fn temp_file(&mut self, tf: TempFileType) -> &mut Self

Write the /TF attribute to control permissions to write a temporary file.

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

pub fn len(&self) -> i32

The number of written pairs.

pub fn is_empty(&self) -> bool

Whether no pairs have been written so far.

pub fn insert(&mut self, key: Name<'_>) -> Obj<'_>

Start writing a pair with an arbitrary value.

pub fn pair<T: Primitive>(&mut self, key: Name<'_>, value: T) -> &mut Self

Write a pair with a primitive value.

This is a shorthand for dict.insert(key).primitive(value).

pub fn pairs<'n, T: Primitive>( &mut self, pairs: impl IntoIterator<Item = (Name<'n>, T)>, ) -> &mut Self

Write a sequence of pairs with primitive values.
