Struct alsa_ctl_tlv_codec::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.

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

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.
