Struct diesel::pg::types::sql_types::Record

pub struct Record<ST>(_);

The Record (a.k.a. tuple) SQL type.

ToSql impls

• Any tuple which can be serialized to each of the elements (note: There are major caveats, see the section below)

FromSql impls

• Any tuple which can be deserialized from each of the elements.

Caveats about serialization

Typically in the documentation for SQL types, we use "FromSql impls" as a shorthand for "Rust types that you can use to represent this type". For every other type, that means there is specifically an implementation of the FromSql trait.

However, PostgreSQL does not support transmission of anonymous record types as bind parameters. It only supports transmission for named composite types. For this reason, if you tried to do int_tuple_col.eq((1, 2)), we will generate the SQL int_tuple_col = ($1, $2) rather than int_tuple_col = $1 as we would for anything else.

This should not be visible during normal usage. The only time this would affect you is if you were attempting to use sql_query with tuples. Your code would not compile in that case, as the ToSql trait itself is not implemented.

You can implement ToSql for named composite types. See WriteTuple for details.
