Enum ParamRef 

pub enum ParamRef<'a> {
    Null,
    I64(i64),
    U64(u64),
    F64(f64),
    Date(&'a Date),
    Time(&'a Time),
    DateTime(&'a DateTime),
    DateTimeTz(&'a DateTimeTz),
    Uuid(&'a [u8; 16]),
    Str(&'a str),
    Bytes(&'a [u8]),
}

A borrowed SQL parameter value.

This is the low-level view used by ParamSource.

Most code does not need to construct ParamRef directly. It is mainly for custom ParamSource implementations that already have values stored in their own format and want to expose borrowed parameters without first copying them into Params.

Variants

Null

A date.

Time(&'a Time)

A time of day.

DateTime(&'a DateTime)

A date and time without an offset.

DateTimeTz(&'a DateTimeTz)
