Struct Container 

pub struct Container {
    pub entries: Vec<TlvItem>,
}

The data to express container to aggregate multiple data for TLV (Type-Length-Value) of ALSA control interface.

It has SNDRV_CTL_TLVT_CONTAINER (=0) in its type field and has variable number of elements in value field.

Fields

entries: Vec<TlvItem>

The entries of data for TLV.

Trait Implementations

impl Clone for Container

fn clone(&self) -> Container

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Container

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

Formats the value using the given formatter.

impl From<&Container> for Vec<u32>

fn from(data: &Container) -> Self

Converts to this type from the input type.

impl From<Container> for Vec<u32>

fn from(data: Container) -> Self

Converts to this type from the input type.

impl PartialEq for Container

fn eq(&self, other: &Container) -> 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<'a> TlvData<'a> for Container

fn value_type(&self) -> u32

Return the value of type field. It should come from UAPI of Linux kernel.

fn value_length(&self) -> usize

Return the length of value field. It should be in byte unit and multiples of 4 as result.

fn value(&self) -> Vec<u32>

Generate vector with u32 element for raw data.

impl ToDbInterval for Container

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

impl ToValueRange for Container

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

impl TryFrom<&[u32]> for Container

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 Container

impl StructuralPartialEq for Container
