decl_macros

Macros

call_if_true

Syntactic sugar to run a conditional statement. Here’s an example.

debug

This is a really simple macro to make it effortless to use the color console logger. It takes a single identifier as an argument, or any number of them. It simply dumps an arrow symbol, followed by the identifier (stringify’d) along with the value that it contains (using the Debug formatter). All of the output is colorized for easy readability. You can use it like this.

fire_and_forget

Declarative macro to surround the given block with a call to tokio::spawn. This is useful for spawning a task that will run in the background from a function that is NOT async.

make_api_call_for

Declarative macro to generate the API call functions. This adds the following:

print_header

throws

Wrap the given block or stmt so that it returns a Result<()>. It is just syntactic sugar that helps having to write Ok(()) repeatedly.

unwrap_option_or_compute_if_none

Unwrap the $option, and if None then run the $next closure which must return a value that is set to $option. Basically a way to compute something lazily when it (the Option) is set to None.

unwrap_option_or_run_fn_returning_err

Unwrap the $option, and if None then run the $next closure which must return an error. This macro must be called in a block that returns a ResultCommon<T>.

with

Runs the $code block after evaluating the $eval expression and assigning it to $id.

with_mut

Similar to with! except $id is a mutable reference to the $eval expression.
