Struct discid::Features

pub struct Features { /* fields omitted */ }

Constants representing the features supported by libdiscid.

See DiscId::read_features for details.

Methods

impl Features

pub const READ: Features

Read the CD TOC.

This is supported on all platforms and indicates that only the table of contents (TOC), from which the disc ID gets calculated, will be read.

pub const MCN: Features

Read the MCN (aka barcode) information.

Read the MCN field from the CD. Not all CDs provide this information. Without this feature DiscId::mcn will always return an empty string.

pub const ISRC: Features

Supports reading the ISRCs per track.

For each track read the ISRC encoded in the subchannel data. Not all CDs provide this information. Without this feature Track::isrc will always be an empty string.

pub fn empty() -> Features

Returns an empty set of flags.

pub fn all() -> Features

Returns the set containing all flags.

pub fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<Features>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub fn from_bits_truncate(bits: u32) -> Features

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub fn intersects(&self, other: Features) -> bool

Returns true if there are flags common to both self and other.

pub fn contains(&self, other: Features) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: Features)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: Features)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: Features)

Toggles the specified flags in-place.

pub fn set(&mut self, other: Features, value: bool)

Inserts or removes the specified flags depending on the passed value.
