Lifecycle state of a descriptor.

Variants

Public

Fully visible to reads and writes.

AddingField

A new column/field is being added at the given descriptor version.

Fields

since_version: u64

DroppingField

A column/field is being removed at the given descriptor version.

Fields

since_version: u64

Dropping

The entire descriptor is being dropped; visible only for in-flight queries planned before since_version.

Fields

since_version: u64

OfflineRebuilding

An index or MV is being rebuilt offline.

Implementations

impl DescriptorState

pub fn is_public(&self) -> bool

Trait Implementations

impl Clone for DescriptorState

fn clone(&self) -> DescriptorState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DescriptorState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DescriptorState

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 DescriptorState

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 DescriptorState

fn eq(&self, other: &DescriptorState) -> 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 DescriptorState

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 DescriptorState

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

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

impl Eq for DescriptorState
