Struct DatanodeTableKey

pub struct DatanodeTableKey {
    pub datanode_id: DatanodeId,
    pub table_id: TableId,
}

The key mapping {datanode_id} to {table_id}

The layout: __dn_table/{datanode_id}/{table_id}.

Fields

datanode_id: DatanodeId

table_id: TableId

Trait Implementations

impl Clone for DatanodeTableKey

fn clone(&self) -> DatanodeTableKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DatanodeTableKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DatanodeTableKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DatanodeTableKey

impl MetadataKey<'_, DatanodeTableKey> for DatanodeTableKey

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

fn from_bytes(bytes: &[u8]) -> Result<DatanodeTableKey>

impl MetadataKeyGetTxnOp for DatanodeTableKey

fn build_get_op( &self, ) -> (TxnOp, impl for<'a> FnMut(&'a mut TxnOpGetResponseSet) -> Option<Vec<u8>>)

Returns a TxnOp to retrieve the corresponding value and a filter to retrieve the value from the TxnOpGetResponseSet

impl PartialEq for DatanodeTableKey

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