Conversion from rust values to Oracle values.

The type of the Oracle value is determined by the rust type.

Rust Type	Oracle Type	Oracle Value
str, String	nvarchar2(length of the rust value)	The specified value
i8, i16, i32, i64, isize, u8, u16, u32, u64, usize, f32, f64	number	The specified value
Vec\<u8>	raw(length of the rust value)	The specified value
bool	boolean (PL/SQL only)	The specified value
Timestamp	timestamp(9) with time zone	The specified value
IntervalDS	interval day(9) to second(9)	The specified value
IntervalYM	interval year(9) to month	The specified value
Collection	type returned by Collection::object_type	The specified value
Object	type returned by Object::object_type	The specified value
Option\<T> where T: ToSql + ToSqlNull	When the value is Some, the contained value decides the Oracle type. When it is None, ToSqlNull decides it.	When the value is Some, the contained value. When it is None, a null value.
OracleType	type represented by the OracleType.	a null value
(&ToSql, &OracleType)	type represented by the second element.	The value of the first element

When you need to bind output parameters such as varchar2, use OracleType or (&ToSql, &OracleType) to specify the maximum length of data types.

When chrono feature is enabled, the following conversions are added.

Rust Type	Oracle Type
chrono::Date	timestamp(0) with time zone
chrono::DateTime	timestamp(9) with time zone
chrono::naive::NaiveDate	timestamp(0)
chrono::naive::NaiveDateTime	timestamp(9)
chrono::Duration	interval day(9) to second(9)
