Enum alto_logger::TimeConfig

#[non_exhaustive]
pub enum TimeConfig {
    None,
    Unix,
    Relative(Instant),
    Timing(Mutex<Option<Instant>>),
    DateTime(&'static [FormatItem<'static>]),
}

How the timestamp should be displayed

Several helper methods for constructing this type are provided

• Relative timestamp style
  • use TimeConfig::relative_now to start the clock from now
• Timing timestamp style
  • use TimeConfig::relative_local.

Note Defaults to the None timestamp

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

No timestamp

Unix

Timestamp since the UNIX epoch

Relative(Instant)

Relative timestamp from the start of the program

This prints out a fractional number of seconds from when the logger was initialized.

Timing(Mutex<Option<Instant>>)

Relative timestamp from the previous log statement

This prints out a fractional number of seconds since the last statement was logged

DateTime(&'static [FormatItem<'static>])

Timestamp formatted with from UTC ‘now’. See formatting

This allows you to provide a ‘fixed’ date time. (e.g. UTC offset or unix timestamp or whatever you want)

Implementations

impl TimeConfig

pub fn relative_now() -> Self

Create a Relative timestamp starting at ‘now’

pub fn relative_local() -> Self

Create a Relative timestamp based on the previous logging statement

pub fn unix_timestamp() -> Self

Create a timestamp based on the UNIX epoch (number of seconds since Jan. 1 1970)

pub fn date_time_format(
    format_description: &'static [FormatItem<'static>]
) -> Self

Create a DateTime format

See the formatting description here

This requires you to use a statically-parsed format_description.

you can get one via format_description or using a well-known format
