Enum OwnedMySQLValue 

pub enum OwnedMySQLValue {
    Null,
    Bytes(Vec<u8>),
    Int(i64),
    UInt(u64),
    Float(f32),
    Double(f64),
    Date {
        year: u16,
        month: u8,
        day: u8,
        hour: u8,
        minute: u8,
        second: u8,
        microseconds: u32,
    },
    Time {
        negative: bool,
        days: u32,
        hours: u8,
        minutes: u8,
        seconds: u8,
        microseconds: u32,
    },
}

A MySQLValue that owns its bytes, for storing parameters beyond the borrow (for example in a cached prepared statement).

Convert with MySQLValue::into_owned or From. SQL::into_owned() does not do this for you: it owns the chunk list but keeps the parameter type.

Variants

Null

SQL NULL.

Bytes(Vec<u8>)

Owned text, binary, decimal, JSON, enum, or set bytes.

Int(i64)

Signed integer payload.

UInt(u64)

Unsigned integer payload.

Float(f32)

Single-precision floating-point payload.

Double(f64)

Double-precision floating-point payload.

Date
