Required Methods§

Source

fn list_functions<'life0, 'async_trait>( &'life0 self, request: ListFunctionsRequest, context: Cx, ) -> Pin<Box<dyn Future<Output = Result<ListFunctionsResponse>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

List functions

List functions within the specified parent catalog and schema. If the caller is the metastore admin, all functions are returned in the response. Otherwise, the caller must have USE_CATALOG on the parent catalog and USE_SCHEMA on the parent schema, and the function must either be owned by the caller or have SELECT on the function.

Source

fn create_function<'life0, 'async_trait>( &'life0 self, request: CreateFunctionRequest, context: Cx, ) -> Pin<Box<dyn Future<Output = Result<Function>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Create a function

Creates a new function. The caller must be a metastore admin or have the CREATE_FUNCTION privilege on the parent catalog and schema.

Source

fn get_function<'life0, 'async_trait>( &'life0 self, request: GetFunctionRequest, context: Cx, ) -> Pin<Box<dyn Future<Output = Result<Function>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Get a function

Gets a function from within a parent catalog and schema. For the fetch to succeed, the caller must be a metastore admin, the owner of the function, or have SELECT on the function.

Source

fn update_function<'life0, 'async_trait>( &'life0 self, request: UpdateFunctionRequest, context: Cx, ) -> Pin<Box<dyn Future<Output = Result<Function>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Update a function

Updates the function that matches the supplied name. Only the owner of the function can be updated.

Source

fn delete_function<'life0, 'async_trait>( &'life0 self, request: DeleteFunctionRequest, context: Cx, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Delete a function

Deletes the function that matches the supplied name. For the deletion to succeed, the caller must be the owner of the function.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
