Enum Nullability

pub enum Nullability {
    NoNulls(Box<NoNull>),
    SomeNulls(Box<SomeNull>),
    AllNulls(AllNull),
}

Variants

NoNulls(Box<NoNull>)

The array has no nulls and there is a single buffer needed

SomeNulls(Box<SomeNull>)

The array may have nulls and we need two buffers

AllNulls(AllNull)

All values are null (no buffers needed)

Implementations

impl Nullability

pub fn encode(&self, buf: &mut impl BufMut)

Encodes the message to a buffer.

pub fn merge( field: &mut Option<Nullability>, tag: u32, wire_type: WireType, buf: &mut impl Buf, ctx: DecodeContext, ) -> Result<(), DecodeError>

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for Nullability

fn clone(&self) -> Nullability

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Nullability

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

Formats the value using the given formatter.

impl PartialEq for Nullability

fn eq(&self, other: &Nullability) -> 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.
