Struct Data

pub struct Data<'a> {
    pub points: Cow<'a, [DacPoint]>,
}

Indicates to the DAC to add the following point data into its buffer.

Point data is laid out as follows:

• 0x64
• : u16

Fields

points: Cow<'a, [DacPoint]>

Implementations

impl<'a> Data<'a>

pub fn read_n_points<R>(reader: R) -> Result<u16>

where R: ReadBytesExt,

Read the u16 representing the number of points within the Data from the given reader.

This method is useful for determining how many more bytes should be read from a stream.

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

pub fn read_points<R>( reader: R, n_points: u16, points: &mut Vec<DacPoint>, ) -> Result<()>

where R: ReadBytesExt,

Read and append the given number of points into the given Vec of DacPoints.

This method is useful as an alternative to Self::read_fields or Self::read_from_bytes as it allows for re-using a buffer of points rather than dynamically allocating a new one each time.

Note that if reading from a stream, this method assumes that the starting command byte and the u16 representing the number of points have both already been read.

impl Data<'static>

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

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

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

Trait Implementations

impl<'a> Clone for Data<'a>

fn clone(&self) -> Data<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Command for Data<'a>

const START_BYTE: u8 = 100u8

The starting byte of the command.

fn start_byte(&self) -> u8

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

impl<'a> Debug for Data<'a>

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

Formats the value using the given formatter.

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

fn from(command: Data<'a>) -> Self

Converts to this type from the input type.

impl<'a> Hash for Data<'a>

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<'a> PartialEq for Data<'a>

fn eq(&self, other: &Data<'a>) -> 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 Data<'static>

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

Read the command from bytes.

impl<'a> WriteToBytes for Data<'a>

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

Write the command to bytes.

impl<'a> Eq for Data<'a>

impl<'a> StructuralPartialEq for Data<'a>
