An enum that holds different types of data defined by Table 3-5 Well-known data types.

Variants

Reserved(Vec<u8>)

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

Utf8(String)

A value containing a String decoded from, or to be encoded to utf-8.

Utf16(String)

A value containing a String decoded from, or to be encoded to utf-16.

Jpeg(Vec<u8>)

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

Png(Vec<u8>)

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

BeSigned(Vec<u8>)

A value containing big endian signed integer inside a Vec<u8>.

Implementations

impl Data

pub fn len(&self) -> usize

Returns the length in bytes.

pub fn is_empty(&self) -> bool

Returns true if the data is empty.

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

Attempts to write the typed data to the writer.

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

Attempts to write the raw data to the writer.

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: &Data) -> bool

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

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

This method tests for !=.
