Enum DataIdent

pub enum DataIdent {
    Fourcc(Fourcc),
    Freeform {
        mean: Cow<'static, str>,
        name: Cow<'static, str>,
    },
}

The identifier used to store metadata inside an item list. Either a Fourcc or an freeform identifier.

Variants

Fourcc(Fourcc)

A standard identifier containing a 4 byte atom identifier.

Freeform

An identifier of a freeform (----) atom containing either owned or static mean and name strings.

Fields

mean: Cow<'static, str>

The mean string, typically in reverse domain notation.

Most commonly this is "com.apple.iTunes". See APPLE_ITUNES_MEAN.

name: Cow<'static, str>

The name string used to identify the freeform atom.

Implementations

impl DataIdent

pub fn freeform( mean: impl Into<Cow<'static, str>>, name: impl Into<Cow<'static, str>>, ) -> Self

Creates a new identifier of type DataIdent::Freeform containing the owned mean, and name string.

pub const fn fourcc(bytes: [u8; 4]) -> Self

Creates a new identifier of type DataIdent::Fourcc containing an atom identifier with the 4-byte identifier.

Trait Implementations

impl Clone for DataIdent

fn clone(&self) -> DataIdent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataIdent

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

Formats the value using the given formatter.

impl Display for DataIdent

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

Formats the value using the given formatter.

impl From<Fourcc> for DataIdent

fn from(value: Fourcc) -> Self

Converts to this type from the input type.

impl<'a> From<FreeformIdent<'a, BorrowedStr<'a>>> for DataIdent

fn from(value: FreeformIdent<'a, BorrowedStr<'a>>) -> Self

Converts to this type from the input type.

impl From<FreeformIdent<'static, StaticStr<'static>>> for DataIdent

fn fourcc(&self) -> Option<Fourcc>

Returns a 4 byte atom identifier.

impl PartialEq<DataIdent> for Fourcc

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for DataIdent
