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 fn with(ident: Ident, offset: usize, content: ContentT) -> Self

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

pub fn with_raw_data(ident: Ident, offset: usize, data: DataT) -> Self

Creates an atom template containing ContentT::RawData with the provided data template.

pub 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 mut_child(&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(&self) -> Option<&Self>

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

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

Returns a mutable reference to 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

fn clone(&self) -> AtomT

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AtomT

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

Formats the value using the given formatter.

impl PartialEq<AtomT> for AtomT

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

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

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

This method tests for !=.
