# Enum chrono::SecondsFormat [−] [src]

    pub enum SecondsFormat {
        Secs,
        Millis,
        Micros,
        Nanos,
        AutoSi,
        // some variants omitted
    }

Specific formatting options for seconds. This may be extended in the future, so exhaustive matching in external code is not recommended.

See the `TimeZone::to_rfc3339_opts` function for usage.

## Variants

`Secs`

Format whole seconds only, with no decimal point nor subseconds.

`Millis`

Use fixed 3 subsecond digits. This corresponds to Fixed::Nanosecond3.

`Micros`

Use fixed 6 subsecond digits. This corresponds to Fixed::Nanosecond6.

`Nanos`

Use fixed 9 subsecond digits. This corresponds to Fixed::Nanosecond9.

`AutoSi`

Automatically select one of `Secs`, `Millis`, `Micros`, or `Nanos` to display all available non-zero sub-second digits. This corresponds to Fixed::Nanosecond.
