Enum mp4ameta::Data

pub enum Data {
    Reserved(Vec<u8>),
    Utf8(String),
    Utf16(String),
    Jpeg(Vec<u8>),
    Png(Vec<u8>),
    Unparsed(i32),
}

A struct that holds the different types of data an Atom can contain following Table 3-5 Well-known data types.

Variants

Reserved(Vec<u8>)

A value containing reserved type data inside a Option<Vec<u8>>.

Utf8(String)

A value containing a Option<String> decoded from utf-8.

Utf16(String)

A value containing a Option<String> decoded from utf-16.

Jpeg(Vec<u8>)

A value containing jpeg byte data inside a Option<Vec<u8>>.

Png(Vec<u8>)

A value containing png byte data inside a Option<Vec<u8>>.

Unparsed(i32)

A value containing a u32 determining the datatype of the data that is yet to be parsed.

Methods

impl Data

pub fn len(&self) -> usize

Returns the length in bytes.

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

Attempts to parse itself from the reader.

pub fn write_typed(&self, writer: &mut impl Write) -> Result<()>

pub fn write_raw(&self, writer: &mut impl Write) -> Result<()>

pub fn read_to_u8_vec(
    reader: &mut impl Read + Seek,
    length: usize
) -> Result<Vec<u8>>

Attempts to read 8 bit unsigned integers from the reader to a vector of size length.

pub fn read_to_u16_vec(
    reader: &mut impl Read + Seek,
    length: usize
) -> Result<Vec<u16>>

Attempts to read 16 bit unsigned integers from the reader to a vector of size length.

pub fn read_utf8(reader: &mut impl Read + Seek, length: usize) -> Result<String>

Attempts to read a utf-8 string from the reader.

pub fn read_utf16(
    reader: &mut impl Read + Seek,
    length: usize
) -> Result<String>

Attempts to read a utf-16 string from the reader.

Trait Implementations

impl Clone for Data

fn clone(&self) -> Data

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Data

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

Formats the value using the given formatter.

impl PartialEq<Data> for Data

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

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

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

This method tests for !=.
