Struct DbRange 

pub struct DbRange {
    pub entries: Vec<DbRangeEntry>,
}

The data to express multiple ranges in the state of control element for dB expression. It has SNDRV_CTL_TLVT_DB_RANGE (=3) in its type field and has variable number of elements in value field.

Fields

entries: Vec<DbRangeEntry>

The entries of ranges for dB expression.

Trait Implementations

impl Clone for DbRange

fn clone(&self) -> DbRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DbRange

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

Formats the value using the given formatter.

impl From<&DbRange> for Vec<u32>

fn from(data: &DbRange) -> Self

Converts to this type from the input type.

impl From<DbRange> for Vec<u32>

fn from(data: DbRange) -> Self

Converts to this type from the input type.

impl PartialEq for DbRange

fn eq(&self, other: &DbRange) -> 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 DbRange

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 DbRange

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

impl ToValueRange for DbRange

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

impl TryFrom<&[u32]> for DbRange

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.
