Trait sqlx_core::executor::Execute

pub trait Execute<'q, DB: Database>: Send + Sized {
    // Required methods
    fn sql(&self) -> &'q str;
    fn statement(&self) -> Option<&DB::Statement<'q>>;
    fn take_arguments(
        &mut self,
    ) -> Result<Option<<DB as Database>::Arguments<'q>>, BoxDynError>;
    fn persistent(&self) -> bool;
}

A type that may be executed against a database connection.

Implemented for the following:

• &str
• Query

Required Methods

fn sql(&self) -> &'q str

Gets the SQL that will be executed.

fn statement(&self) -> Option<&DB::Statement<'q>>

Gets the previously cached statement, if available.

fn take_arguments( &mut self, ) -> Result<Option<<DB as Database>::Arguments<'q>>, BoxDynError>

Returns the arguments to be bound against the query string.

Returning Ok(None) for Arguments indicates to use a “simple” query protocol and to not prepare the query. Returning Ok(Some(Default::default())) is an empty arguments object that will be prepared (and cached) before execution.

Returns Err if encoding any of the arguments failed.

fn persistent(&self) -> bool

Returns true if the statement should be cached.

Object Safety

This trait is not object safe.
