Struct diesel::pg::types::sql_types::Array[−][src]

pub struct Array<ST>(_);

Expand description

The Array SQL type.

This wraps another type to represent a SQL array of that type. Multidimensional arrays are not supported, nor are arrays containing null.

`ToSql` impls

Vec<T> for any T which implements ToSql<ST>
&[T] for any T which implements ToSql<ST>

`FromSql` impls

Vec<T> for any T which implements ToSql<ST>
