Struct SnapshotHeader 

pub struct SnapshotHeader {
    pub array: String,
    pub coord_range: CoordRange,
    pub total_chunks: u32,
    pub snapshot_hlc: Hlc,
    pub schema_hlc: Hlc,
}

Metadata header sent before the chunk stream begins.

Receivers use this to pre-allocate storage and validate completeness.

Fields

array: String

Name of the target array collection.

coord_range: CoordRange

Coord range covered by this snapshot.

total_chunks: u32

Number of SnapshotChunks that will follow.

snapshot_hlc: Hlc

HLC at which the snapshot was taken.

schema_hlc: Hlc

HLC of the schema in effect when this snapshot was taken.

Trait Implementations

impl Clone for SnapshotHeader

fn clone(&self) -> SnapshotHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SnapshotHeader

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for SnapshotHeader

fn read<R: Read<'__msgpack_de>>(reader: &mut R) -> Result<Self, Error>

where Self: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl PartialEq for SnapshotHeader

fn eq(&self, other: &SnapshotHeader) -> 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 Serialize for SnapshotHeader

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToMessagePack for SnapshotHeader

fn write<W: Write>(&self, writer: &mut W) -> Result<(), Error>

Writes the MessagePack representation of this value into the provided writer.
