Enum TrackPosition 

pub enum TrackPosition {
    Invalid,
    First,
    Middle,
    Last,
    Only,
}

Track Position.

This enum is used to differentiate between first, middle, and final track positions within the context of a given table of contents.

Variants of this type are returned by Track::position.

Variants

Invalid

Invalid.

This is used for track numbers that are out of range, including pre-gap hidden tracks (#0).

First

The First Track.

Middle

Somewhere in the Middle.

Last

The Last Track.

Only

The Only Track.

Implementations

impl TrackPosition

pub const fn is_valid(self) -> bool

Is Valid?

Returns true if the position is anything other than TrackPosition::Invalid.

pub const fn is_first(self) -> bool

Is First?

This returns true if the track appears at spot #1 on the disc.

Examples

use cdtoc::TrackPosition;

// Yep!
assert!(TrackPosition::First.is_first());
assert!(TrackPosition::Only.is_first());

// Nope!
assert!(! TrackPosition::Middle.is_first());
assert!(! TrackPosition::Last.is_first());

pub const fn is_last(self) -> bool

Is Last?

This returns true if the track appears at the end of the disc.

Examples

use cdtoc::TrackPosition;

// Yep!
assert!(TrackPosition::Last.is_last());
assert!(TrackPosition::Only.is_last());

// Nope!
assert!(! TrackPosition::First.is_last());
assert!(! TrackPosition::Middle.is_last());

pub const fn as_str(self) -> &'static str

As Str.

Return the equivalent string slice for the variant.

Trait Implementations

impl Clone for TrackPosition

fn clone(&self) -> TrackPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrackPosition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TrackPosition

Available on crate feature serde only.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<(u16, u16)> for TrackPosition

fn from(src: (u16, u16)) -> Self

Converts to this type from the input type.

impl From<(u32, u32)> for TrackPosition

fn from(src: (u32, u32)) -> Self

Converts to this type from the input type.

impl From<(u64, u64)> for TrackPosition

fn from(src: (u64, u64)) -> Self

Converts to this type from the input type.

impl From<(u8, u8)> for TrackPosition

fn from(src: (u8, u8)) -> Self

Converts to this type from the input type.

impl Hash for TrackPosition

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for TrackPosition

fn eq(&self, other: &TrackPosition) -> 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.
