Trait oracle::FromSql

pub trait FromSql {
    fn from_sql(val: &SqlValue) -> Result<Self>
    where
        Self: Sized;
}

A trait to convert 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 Type	Rust Type
CHAR, NCHAR, VARCHAR2, NVARCHAR2	String
″	i8, i16, i32, i64, u8, u16, u32, u64 by String.parse()
...	...

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

Required Methods

fn from_sql(val: &SqlValue) -> Result<Self> where
    Self: Sized,
