Dyn-safe trait for table operations.

Required Methods

fn table_name(&self) -> &str

fn table_alias(&self) -> &str

fn column_names(&self) -> Vec<String>

fn add_condition(&mut self, condition: Box<dyn Any + Send + Sync>) -> Result<()>

Add a condition to this table using a type-erased expression The expression must be of type T::Expr for the underlying table’s TableSource

fn temp_add_condition( &mut self, condition: AnyExpression, ) -> Result<ConditionHandle>

Add a temporary condition using AnyExpression that can be removed later

fn temp_remove_condition(&mut self, handle: ConditionHandle) -> Result<()>

Remove a temporary condition by its handle

fn search_expression(&self, search_value: &str) -> Result<AnyExpression>

Create a search expression for this table

fn clone_box(&self) -> Box<dyn TableLike<Value = Self::Value, Id = Self::Id>>

Clone into a Box for object-safe cloning

fn into_any(self: Box<Self>) -> Box<dyn Any>

Convert to Any for downcasting

fn as_any_ref(&self) -> &dyn Any

fn set_pagination(&mut self, pagination: Option<Pagination>)

Set pagination for this table

fn get_pagination(&self) -> Option<&Pagination>

Get pagination for this table

fn get_count<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<i64>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get count of records in the table

Provided Methods

fn get_ref(&self, _relation: &str) -> Result<AnyTable>

Traverse a named reference and return the related table as AnyTable.

Default impl returns an error so wrappers without ref support compile unchanged. Table<T, E> overrides this to delegate to its inherent get_ref; AnyTable, CborAdapter and LiveTable override to forward through to the underlying table that holds the refs.

Implementors

impl TableLike for AnyTable

impl<T, E> TableLike for Table<T, E>
