Struct mz_expr::row::collection::EncodedRowMetadata

pub struct EncodedRowMetadata {
    offset: usize,
    diff: NonZeroUsize,
}

Inner type of RowCollection, describes a single Row.

Fields

offset: usize

Offset into the binary blob of encoded rows.

TODO(parkmycar): Consider making this a u32.

diff: NonZeroUsize

Diff for the Row.

TODO(parkmycar): Consider making this a smaller type, note that some compute introspection collections, e.g. mz_scheduling_elapsed_raw, encodes nano seconds in the diff field which requires a u64.

Trait Implementations

impl Clone for EncodedRowMetadata

fn clone(&self) -> EncodedRowMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EncodedRowMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EncodedRowMetadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EncodedRowMetadata

fn eq(&self, other: &EncodedRowMetadata) -> 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 RustType<ProtoEncodedRowMetadata> for EncodedRowMetadata

fn into_proto(&self) -> ProtoEncodedRowMetadata

Convert a Self into a Proto value.

fn from_proto(proto: ProtoEncodedRowMetadata) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.

impl Serialize for EncodedRowMetadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
