pub struct MessageHeader(pub u8);

---

The root Message type This union enables us to easily send different message types without redundant storage, and in the future we can easily add new message types.

Arrow implementations do not need to implement all of the message types, which may include experimental metadata types. For maximum compatibility, it is best to send data using RecordBatch

Trait Implementations

impl Clone for MessageHeader

fn clone(&self) -> MessageHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MessageHeader

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

Formats the value using the given formatter.

impl Default for MessageHeader

fn default() -> MessageHeader

Returns the “default value” for a type.

impl EndianScalar for MessageHeader

type Scalar = u8

fn to_little_endian(self) -> u8

fn from_little_endian(v: u8) -> MessageHeader

impl<'a> Follow<'a> for MessageHeader

type Inner = MessageHeader

unsafe fn follow( buf: &'a [u8], loc: usize, ) -> <MessageHeader as Follow<'a>>::Inner

Safety

impl Hash for MessageHeader

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

where __H: Hasher,

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 Ord for MessageHeader

fn cmp(&self, other: &MessageHeader) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for MessageHeader

fn eq(&self, other: &MessageHeader) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for MessageHeader

fn partial_cmp(&self, other: &MessageHeader) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Push for MessageHeader

type Output = MessageHeader

unsafe fn push(&self, dst: &mut [u8], _written_len: usize)

Safety

fn size() -> usize

fn alignment() -> PushAlignment

impl<'a> Verifiable for MessageHeader

fn run_verifier( v: &mut Verifier<'_, '_>, pos: usize, ) -> Result<(), InvalidFlatbuffer>

Runs the verifier for this type, assuming its at position pos in the verifier’s buffer. Should not need to be called directly.
