Conversion from Oracle values to rust values.

Values in Oracle are converted to Rust type as possible as it can. The following table indicates supported conversion.

Oracle TypeRust Type
character data typesString
“i8, i16, i32, i64, isize, u8, u16, u32, u64, usize, f64, f32 by using String.parse()
“Vec<u8> (The Oracle value must be in hexadecimal.)
“Timestamp by String.parse()
“IntervalDS by String.parse()
“IntervalYM by String.parse()
numeric data typesi8, i16, i32, i64, isize, u8, u16, u32, u64, usize, f64, f32
“String
rawVec<u8>
“String (The Oracle value is converted to characters in hexadecimal.)
timestamp data typesTimestamp
“String
interval day to monthIntervalDS
“String
interval year to monthIntervalYM
“String
Oracle object except Oracle collectionObject
“String
Oracle collectionCollection
“String
rowidString
boolean (PL/SQL only)bool

When chrono feature is enabled, the followings are added.

Oracle TypeRust Type
timestamp data typeschrono::DateTime
“chrono::Date
“chrono::naive::NaiveDateTime
“chrono::naive::NaiveDate
interval day to secondchrono::Duration

This conversion is used also to get values from output parameters.
