Trait for sql parser. The parser transforms string query into its statement type.

Required Methods

fn parse_sql<'life0, 'life1, 'life2, 'life3, 'async_trait, C>( &'life0 self, client: &'life1 C, sql: &'life2 str, types: &'life3 [Type], ) -> Pin<Box<dyn Future<Output = PgWireResult<Self::Statement>> + Send + 'async_trait>>

where C: ClientInfo + Unpin + Send + Sync + 'async_trait, Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

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.
