Expand description

Logs to stderr, accepts multiple arguments.

Usage example:

use urs::log;
urs::log!(log::LogType::WARN, "This number is odd: {}!", 5);
urs::log!([info] "Info attribute");
urs::log!([fatal] "This log will be logged with the {} type {}", "Fatal",
    "using [fatal] in the log! macro and exit afterwards");

There are attributes for each logging method:

  • [info]
  • [warn]
  • [error]
  • [fatal]
