Required Methods

fn placeholder(n: usize) -> String

fn auto_increment_pk() -> &'static str

fn rows_affected(res: &Self::QueryResult) -> u64

fn last_insert_id(res: &Self::QueryResult) -> i64

Provided Methods

fn current_timestamp_fn() -> &'static str

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.
