Struct Begin

pub struct Begin {
    pub low_water_mark: u16,
    pub point_rate: u32,
}

Causes the DAC to begin producing output.

If the playback system was Prepared and there was data in the buffer, then the DAC will reply with ACK.

Otherwise, it replies with NAK - Invalid.

Fields

low_water_mark: u16

Currently unused.

point_rate: u32

The number of points per second to be read from the buffer.

Implementations

impl Begin

pub fn read_fields<R: ReadBytesExt>(reader: R) -> Result<Self>

Consecutively read the fields of the Begin type and return a Begin instance.

Note that if reading from a stream, this method assumes that the starting command byte has already been read.

Trait Implementations

impl Clone for Begin

fn clone(&self) -> Begin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Command for Begin

const START_BYTE: u8 = 98u8

The starting byte of the command.

fn start_byte(&self) -> u8

A provided method for producing the start byte. Useful for trait objects.

impl Debug for Begin

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

Formats the value using the given formatter.

impl<'a> From<Begin> for Command<'a>

fn from(command: Begin) -> Self

Converts to this type from the input type.

impl Hash for Begin

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Begin

fn eq(&self, other: &Begin) -> 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 ReadFromBytes for Begin

fn read_from_bytes<R: ReadBytesExt>(reader: R) -> Result<Self>

Read the command from bytes.

impl SizeBytes for Begin

const SIZE_BYTES: usize = 7usize

impl WriteToBytes for Begin

fn write_to_bytes<W: WriteBytesExt>(&self, writer: W) -> Result<()>

Write the command to bytes.

impl Copy for Begin

impl Eq for Begin

impl StructuralPartialEq for Begin
