Trait ComposerConnectionAsync 

pub trait ComposerConnectionAsync {
    type Value;
    type Statement;
    type Error: From<Error>;

    // Required method
    fn compose(
        &self,
        composer: &Composer,
        template: &Template,
        values: BTreeMap<String, Vec<Self::Value>>,
    ) -> impl Future<Output = Result<(Self::Statement, Vec<Self::Value>), Self::Error>> + Send;
}

Async version of ComposerConnection for async database drivers (e.g. tokio-postgres, mysql_async).

type Value

The database-specific value type for bind parameters.

type Statement

The composed SQL string.

type Error: From<Error>

The error type for this driver.

Required Methods

fn compose( &self, composer: &Composer, template: &Template, values: BTreeMap<String, Vec<Self::Value>>, ) -> impl Future<Output = Result<(Self::Statement, Vec<Self::Value>), Self::Error>> + Send

Compose a template with bind values asynchronously.

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.
