pub struct LoggingTimer<'name> { /* private fields */ }Expand description
When this struct is dropped, it logs a message stating its name and how long the execution time was. Can be used to time functions or other critical areas.
Implementations§
Source§impl<'name> LoggingTimer<'name>
impl<'name> LoggingTimer<'name>
Sourcepub fn new(
file: &'static str,
module_path: &'static str,
line: u32,
name: &'name str,
extra_info: Option<String>,
level: Level,
) -> Option<Self>
pub fn new( file: &'static str, module_path: &'static str, line: u32, name: &'name str, extra_info: Option<String>, level: Level, ) -> Option<Self>
Constructs a new LoggingTimer that prints only a ‘TimerFinished’ message.
This method is not usually called directly, use the timer! macro instead.
Sourcepub fn with_start_message(
file: &'static str,
module_path: &'static str,
line: u32,
name: &'name str,
extra_info: Option<String>,
level: Level,
) -> Option<Self>
pub fn with_start_message( file: &'static str, module_path: &'static str, line: u32, name: &'name str, extra_info: Option<String>, level: Level, ) -> Option<Self>
Constructs a new LoggingTimer that prints a ‘TimerStarting’ and a ‘TimerFinished’ message.
This method is not usually called directly, use the stimer! macro instead.
Sourcepub fn level(self, level: Level) -> Self
👎Deprecated since 0.3: Please use the first parameter to the timer or stimer macro instead
pub fn level(self, level: Level) -> Self
timer or stimer macro insteadSets the logging level. Note that this consumes self, so that it can be called in a one-liner like this:
let tmr = timer!("foo").level(Level::Trace);Sourcepub fn executing(&self, args: Option<Arguments<'_>>)
pub fn executing(&self, args: Option<Arguments<'_>>)
Outputs a log message with a target of ‘TimerExecuting’ showing the current elapsed time, but does not
stop the timer. This method can be called multiple times.
The message can include further information via a format_args! approach.
This method is usually not called directly, it is easier to use the executing! macro.
Sourcepub fn finish(&self, args: Option<Arguments<'_>>)
pub fn finish(&self, args: Option<Arguments<'_>>)
Outputs a log message with a target of ‘TimerFinished’ and suppresses the normal message
that is output when the timer is dropped. The message can include further format_args!
information. This method is normally called using the finish! macro. Calling
finish() again will have no effect.
