pub struct DeferredNow(_);
Expand description

Deferred timestamp creation.

Is used to ensure that a log record that is sent to multiple outputs (in maybe different formats) always uses the same timestamp.

Implementations

Constructs a new instance, but does not generate the timestamp.

Retrieve the timestamp.

Requires mutability because the first caller will generate the timestamp.

Convert into a formatted String.

Panics

Panics if fmt has an inappropriate value.

Enforce the use of UTC rather than local time.

By default, flexi_logger uses or tries to use local time. By calling early in your program either Logger::use_utc() or directly this method, you can override this to always use UTC.

Panics

Panics if called too late, i.e., if DeferredNow::now was already called before on any instance of DeferredNow.
