    start: Instant,
    min_info_time: Duration,
    min_warn_time: Duration,
    description: &'static str,
    has_finished: bool,
}

A guard that logs code execution time when dropped.

Fields

start: Instant

The time that the code started executing.

min_info_time: Duration

has_finished: bool

Implementations

impl CodeTimer

pub fn start() -> Self

Start timing the execution of a function, method, or other code region.

See CodeTimer::start_desc for more details.

pub fn start_desc(description: &'static str) -> Self

Start timing the execution of a function, method, or other code region.

Returns a guard that finishes timing the code when dropped, or when CodeTimer::finish_inner() is called with an empty description.

pub fn finish_desc(self, description: &'static str)

Finish timing the execution of a function, method, or other code region.

pub fn ignore(self)

Ignore this timer: it will not check the elapsed time or log any warnings.

pub fn finish_inner( &mut self, file: impl Into<Option<&'static str>>, line: impl Into<Option<u32>>, description: &'static str, )

Finish timing the execution of a function, method, or other code region.

Trait Implementations

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

Formats the value using the given formatter.

impl Drop for CodeTimer

fn drop(&mut self)

Executes the destructor for this type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
