Enum mysql::Value
[−]
[src]
pub enum Value {
NULL,
Bytes(Vec<u8>),
Int(i64),
UInt(u64),
Float(f64),
Date(u16, u8, u8, u8, u8, u8, u32),
Time(bool, u32, u8, u8, u8, u32),
}Value enumerates possible values in mysql cells. Also Value used to fill
prepared statements.
Note that to receive something different than Value::NULL or Value::Bytes from mysql
you should use prepared statements.
If you want to get something more useful from Value you should implement
FromValue on it. To get T: FromValue from
nullable value you should rely on FromValue implemented on Option<T>.
To convert something to Value you should implement Into<Value> for it.
use mysql::value::from_row; let mut conn = pool.get_conn().unwrap(); let result = conn.prep_exec("SELECT ? * ?", (20i32, 0.8_f32)).unwrap(); for row in result { let c = from_row::<f32>(row.unwrap()); assert_eq!(c, 16.0_f32); }
