[−][src]Struct sqlx::describe::Describe

#[non_exhaustive]pub struct Describe<DB> where
    DB: Database + ?Sized,  {
    pub param_types: Box<[Option<<DB as Database>::TypeInfo>]>,
    pub result_columns: Box<[Column<DB>]>,
}

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<[Option<<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.
