Struct custom_utils::logger::DeferredNow

pub struct DeferredNow(_);

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

impl DeferredNow

pub fn new() -> DeferredNow

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

pub fn now(&mut self) -> &OffsetDateTime

Retrieve the timestamp.

Requires mutability because the first caller will generate the timestamp.

pub fn format(&mut self, fmt: &impl Formattable) -> String

Convert into a formatted String.

Panics

Panics if fmt has an inappropriate value.

pub fn force_utc()

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.

Trait Implementations

impl Debug for DeferredNow

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for DeferredNow

fn default() -> DeferredNow

Returns the “default value” for a type.
