Expand description

SqlDb - SQL Database connections To use this capability, the actor must be linked with the capability contract “wasmcloud:sqldb” wasmbus.contractId: wasmcloud:sqldb wasmbus.providerReceive

Required Methods§

Source

fn execute<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 Context, arg: &'life2 Statement, ) -> Pin<Box<dyn Future<Output = RpcResult<ExecuteResult>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Execute an sql statement

Source

fn query<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 Context, arg: &'life2 Statement, ) -> Pin<Box<dyn Future<Output = RpcResult<QueryResult>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Perform select query on database, returning all result rows

Provided Methods§

Source

fn contract_id() -> &'static str

returns the capability contract id for this interface

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
