Expand description

Traits that provides methods for preparing queries on a DB server.

Required Methods§

Source

fn prepare_tw<'life0, 'async_trait, Q>( self: Pin<&'life0 mut Self>, query: Q, with_tracing: bool, with_warnings: bool, ) -> Pin<Box<dyn Future<Output = Result<PreparedQuery>> + Send + 'async_trait>>
where Q: 'async_trait + ToString + Send, Self: 'async_trait, 'life0: 'async_trait,

It prepares a query for execution, along with query itself the method takes with_tracing and with_warnings flags to get tracing information and warnings.

Provided Methods§

Source

fn prepare<'life0, 'async_trait, Q>( self: Pin<&'life0 mut Self>, query: Q, ) -> Pin<Box<dyn Future<Output = Result<PreparedQuery>> + Send + 'async_trait>>
where Q: 'async_trait + ToString + Send, Self: Send + 'async_trait, 'life0: 'async_trait,

It prepares query without additional tracing information and warnings.

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.
