[−][src]Struct sqlx::describe::Describe
The return type of Executor::describe.
Fields (Non-exhaustive)
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.param_types: Box<[<DB as Database>::TypeInfo]>
The expected types for the parameters of the query.
result_columns: Box<[Column<DB>]>
The type and table information, if any for the results of the query.
