Enum TlvItem 

pub enum TlvItem {
    Container(Container),
    DbRange(DbRange),
    DbScale(DbScale),
    DbInterval(DbInterval),
    Chmap(Chmap),
    Unknown(Vec<u32>),
}

Available items as data of TLV (Type-Length-Value) style in ALSA control interface.

When decoding from data of TLV, use implementation of TryFrom<&[u32]> trait. Data assigned to each enumeration implements TlvData, TryFrom<&[u32], and Vec::<u32>::from(&Self) trait. When decoding to data of TLV, use implementation of Vec::<u32>::from(&Self) for the data.

DbInterval(DbInterval)

Chmap(Chmap)

Unknown(Vec<u32>)

Trait Implementations

impl Clone for TlvItem

fn clone(&self) -> TlvItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TlvItem

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

Formats the value using the given formatter.

impl From<&TlvItem> for Vec<u32>

fn from(item: &TlvItem) -> Self

Converts to this type from the input type.

impl From<TlvItem> for Vec<u32>

fn from(item: TlvItem) -> Self

Converts to this type from the input type.

impl PartialEq for TlvItem

fn eq(&self, other: &TlvItem) -> 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 ToDbInterval for TlvItem

fn to_dbinterval( &self, range: &ValueRange, ) -> Result<DbInterval, ToDbIntervalError>

impl ToValueRange for TlvItem

fn to_valuerange(&self, range: &ValueRange) -> Option<ValueRange>

impl<'a> TryFrom<&'a [u32]> for TlvItem

type Error = TlvDecodeError

The type returned in the event of a conversion error.

fn try_from(raw: &[u32]) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for TlvItem

impl StructuralPartialEq for TlvItem
