Conversions between Rust and standard SQL types.

Types

Rust type	SQL type(s)
bool	BOOLEAN
i16	SMALLINT
i32	INT
i64	BIGINT
f32	FLOAT
f64	DOUBLE
&str, String	VARCHAR, CHAR, TEXT

Nullable

In addition, Option<T> is supported where T implements Type. An Option<T> represents a potentially NULL value from SQL.
