fun_time is a simple Rust library that allows you to easily time your function calls with a simple attribute!
```rust
fn somecoolfunction(avalue: String) -> usize { avalue.len() }
fn main() { let myvaluelength = somecoolfunction(String::from("Hello, world.")); } ```
There are various attributes that allow you to configure the behavior of the fun_time attribute.
message allows you to set a message that will be printed when starting, and when done.when allows you to configure when the timing should be collected. The possible values for this are: "always" which
as the name might suggest will always collect timing information, and "debug" which will only collect when
cfg!(debug_assertions) evaluates to true.give_back is a flag that makes it so the wrapped function will now return the elapsed time instead of printing it.
For this it modifies the return type from for example: -> &'a str to -> (&'a str, std::time::Duration). This
allows you to handle printing or storing the timing information.reporting (can not be used in combination with giveback_) determines how the reporting is done. The possible
options are: "println" which will print to stdout using println!. The "log" option is only available when
the log feature is used. This will use the log crate with info! level logs.The reported messages are formatted as follows:
Start message: "Starting: YOURMESSAGEHERE"
Done message: "YOURMESSAGEHERE: Done in DURATION"
