Enum mp4ameta::ContentT

pub enum ContentT {
    Atoms(Vec<AtomT>),
    RawData(DataT),
    TypedData,
    Empty,
}

A template representing the different types of content an atom template might have.

Variants

Atoms(Vec<AtomT>)

A value containing a list of children atom templates.

RawData(DataT)

A value containing a data template specifying the datatype.

TypedData

A template representing typed data that is defined by a Table 3-5 Well-known data types code prior to the data parsed.

Empty

Empty content.

Implementations

impl ContentT

pub const fn atoms_t() -> Self

Creates a new empty content template of type Self::Atoms.

pub fn atom_t(atom: AtomT) -> Self

Creates a new content template of type Self::Atoms containing the atom template.

pub fn data_atom_t() -> Self

Creates a new content template of type Self::Atoms containing a data atom template.

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

Returns an iterator over the children atoms.

pub fn iter_mut(&mut self) -> IterMut<'_, AtomT>

Returns a mutable iterator over the children atoms.

pub fn child(&self, ident: Ident) -> Option<&AtomT>

Returns a reference to the first children atom matching the identifier, if present.

pub fn first_child(&self) -> Option<&AtomT>

Return a reference to the first children atom, if present.

pub fn child_mut(&mut self, ident: Ident) -> Option<&mut AtomT>

Returns a mutable reference to the first children atom matching the identfier, if present.

pub fn first_child_mut(&mut self) -> Option<&mut AtomT>

Returns a mutable reference to the first children atom, if present.

pub fn take_child(self, ident: Ident) -> Option<AtomT>

Consumes self and returns the first children atom matching the identfier, if present.

pub fn take_first_child(self) -> Option<AtomT>

Consumes self and returns the first children atom, if present.

pub fn parse(
    &self,
    reader: &mut impl Read + Seek,
    length: usize
) -> Result<Content>

Attempts to parse corresponding content from the reader.

Trait Implementations

impl Clone for ContentT

pub fn clone(&self) -> ContentT

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContentT

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

Formats the value using the given formatter.

impl Default for ContentT

pub fn default() -> Self

impl Eq for ContentT

impl IntoIterator for ContentT

type Item = AtomT

The type of the elements being iterated over.

type IntoIter = IntoIter<Self::Item>

Which kind of iterator are we turning this into?

pub fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq<ContentT> for ContentT

pub fn eq(&self, other: &ContentT) -> bool
