Struct DistributedEngine 

pub struct DistributedEngine { /* private fields */ }

Distributed(cluster, database, table[, sharding_key[, policy_name]]) engine definition.

Implementations

impl DistributedEngine

pub fn sharding_key(self, expr: impl Into<String>) -> Self

Add the optional sharding-key expression.

pub fn policy_name(self, name: impl Into<String>) -> Self

Add the optional storage policy name.

pub fn setting( self, name: impl Into<String>, value: impl Into<EngineSettingValue>, ) -> Self

Add one Distributed engine setting.

Trait Implementations

impl Clone for DistributedEngine

fn clone(&self) -> DistributedEngine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DistributedEngine

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

Formats the value using the given formatter.

impl From<DistributedEngine> for TableEngine

fn from(value: DistributedEngine) -> Self

Converts to this type from the input type.

impl PartialEq for DistributedEngine

fn eq(&self, other: &DistributedEngine) -> 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 QueryFragment<ClickHouse> for DistributedEngine

fn walk_ast<'b>(&'b self, out: AstPass<'_, 'b, ClickHouse>) -> QueryResult<()>

Walk over this QueryFragment for all passes.

fn to_sql( &self, out: &mut <DB as Backend>::QueryBuilder, backend: &DB, ) -> Result<(), Error>

Converts this QueryFragment to its SQL representation.

fn collect_binds<'b>( &'b self, out: &mut <DB as Backend>::BindCollector<'b>, metadata_lookup: &mut <DB as TypeMetadata>::MetadataLookup, backend: &'b DB, ) -> Result<(), Error>

Serializes all bind parameters in this query.

fn is_safe_to_cache_prepared(&self, backend: &DB) -> Result<bool, Error>

Is this query safe to store in the prepared statement cache?

fn is_noop(&self, backend: &DB) -> Result<bool, Error>

Does walking this AST have any effect?
