Struct diesel::pg::types::sql_types::Array

pub struct Array<ST>(_);

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>

impl<ST: QueryId> QueryId for Array<ST>

type QueryId = Array<<ST as QueryId>::QueryId>

A type which uniquely represents Self in a SQL query.
