Struct GroupConstruct

pub struct GroupConstruct {
    pub group_config: Option<CompactionConfig>,
    pub parent_group_id: u64,
    pub table_ids: Vec<u32>,
    pub group_id: u64,
    pub new_sst_start_id: u64,
    pub version: i32,
    pub split_key: Option<Vec<u8>>,
}

Fields

group_config: Option<CompactionConfig>

parent_group_id: u64

If parent_group_id is not 0, it means parent_group_id splits into parent_group_id and this group, so this group is not empty initially.

table_ids: Vec<u32>

👎Deprecated

group_id: u64

new_sst_start_id: u64

version: i32

split_key: Option<Vec<u8>>

The split_key is the key that the group is split by. When GroupConstruct with commit_epoch, split_key will be empty When split_key is not None, GroupConstruct tells to use split_key to check each level and split the sstable_info in the level into two groups (bounded by split_key). For the left sstable_info, split_key (right_exclusive=true) will be used as key_range_right. In the current implementation split_key always contains a table_id, vnode = 0, epoch = MAX

Implementations

impl GroupConstruct

pub fn version(&self) -> CompatibilityVersion

Returns the enum value of version, or the default if the field is set to an invalid enum value.

pub fn set_version(&mut self, value: CompatibilityVersion)

Sets version to the provided enum value.

pub fn split_key(&self) -> &[u8]

Returns the value of split_key, or the default value if split_key is unset.

Trait Implementations

impl Clone for GroupConstruct

fn clone(&self) -> GroupConstruct

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GroupConstruct

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

Formats the value using the given formatter.

impl Default for GroupConstruct

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for GroupConstruct

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for GroupConstruct

fn encoded_len(&self) -> usize

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

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

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

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for GroupConstruct

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

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
