Struct mp4ameta::AtomT

pub struct AtomT {
    pub ident: Ident,
    pub offset: usize,
    pub content: ContentT,
}

A template representing a MPEG-4 audio metadata atom.

Fields

ident: Ident

The 4 byte identifier of the atom.

offset: usize

The offset in bytes separating the head from the content.

content: ContentT

The content template of an atom template.

Implementations

impl AtomT

pub const fn new(ident: Ident, offset: usize, content: ContentT) -> Self

Creates an atom template containing the provided content at a n byte offset.

pub const fn data_atom() -> Self

Creates a data atom template containing ContentT::TypedData.

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

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

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

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

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

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

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

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

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

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

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

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

pub fn parse_next(&self, reader: &mut impl Read + Seek) -> Result<Atom>

Attempts to parse an atom, that matches the template, from the reader. This should only be used if the atom has to be in this exact position, if the parsed and expected identifiers don't match this will return an error.

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

Attempts to parse an atom, that matches the template, from the reader.

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

Attempts to parse the atom template's content from the reader.

Trait Implementations

impl Clone for AtomT

pub fn clone(&self) -> AtomT

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AtomT

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

Formats the value using the given formatter.

impl Default for AtomT

pub fn default() -> AtomT

Returns the "default value" for a type.

impl Eq for AtomT

impl PartialEq<AtomT> for AtomT

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

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &AtomT) -> bool

This method tests for !=.
