Trait diesel::deserialize::StaticallySizedRow
source · pub trait StaticallySizedRow<ST, DB: Backend>: FromSqlRow<ST, DB> {
const FIELD_COUNT: usize;
}
Expand description
A marker trait indicating that the corresponding type consumes a static at compile time known number of field
There is normally no need to implement this trait. Diesel provides
wild card impls for all types that implement FromSql<ST, DB>
or Queryable<ST, DB>
where the size of ST
is known
Required Associated Constants§
sourceconst FIELD_COUNT: usize
const FIELD_COUNT: usize
The number of fields that this type will consume.
