Trait Implementations

impl ByteValued for setup_header

fn from_slice(data: &[u8]) -> Option<&Self>

Converts a slice of raw data into a reference of Self.

fn from_mut_slice(data: &mut [u8]) -> Option<&mut Self>

Converts a mutable slice of raw data into a mutable reference of Self.

fn as_slice(&self) -> &[u8]

Converts a reference to self into a slice of bytes.

fn as_mut_slice(&mut self) -> &mut [u8]

Converts a mutable reference to self into a mutable slice of bytes.

fn as_bytes(&mut self) -> VolatileSlice<'_>

Converts a mutable reference to self into a VolatileSlice. This is useful because VolatileSlice provides a Bytes<usize> implementation.

fn zeroed() -> Self

Constructs a Self ewhose binary representation is set to all zeroes.

fn write_all_to<W>(&self, writer: W) -> Result<(), Error>

where W: Write,

Writes this ByteValued’s byte representation to the given Write impl.

fn read_exact_from<R>(reader: R) -> Result<Self, Error>

where R: Read,

Constructs an instance of this ByteValued by reading from the given Read impl.

impl Clone for setup_header

fn clone(&self) -> setup_header

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for setup_header

impl Debug for setup_header

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

Formats the value using the given formatter.

impl Default for setup_header

fn default() -> setup_header

Returns the “default value” for a type.

impl PartialEq for setup_header

fn eq(&self, other: &setup_header) -> 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 StructuralPartialEq for setup_header
