Struct mariadb_sys::Type_handler_hybrid_field_type

#[repr(C)]
pub struct Type_handler_hybrid_field_type {
    pub m_type_handler: *const Type_handler,
}

A handler for hybrid type functions, e.g. COALESCE(), IF(), IFNULL(), NULLIF(), CASE, numeric operators, UNIX_TIMESTAMP(), TIME_TO_SEC().

Makes sure that field_type(), cmp_type() and result_type() are always in sync to each other for hybrid functions.

Fields

m_type_handler: *const Type_handler
