Required Associated Types

type Error: From<GraphQueryError> + Error

Required Methods

fn query<'life0, 'life1, 'async_trait>( &'life0 mut self, stmt: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<GraphQueryOutput, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Execute stmt and return the query output.

Notice

For operation that doesn’t return result, like CREATE TAG, USE space etc. it’s recommended to use execute(stmt).

Provided Methods

fn execute<'life0, 'life1, 'async_trait>( &'life0 mut self, stmt: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Execute stmt and doesn’t return the execution output.

fn show_hosts<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Vec<Host>, Self::Error>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait,

fn show_spaces<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Vec<Space>, Self::Error>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait,
