Crate skip_error

This crate provides a single macro to help skipping a error in a loop, possibly logging it.

For example, imagine you have some code like this.

for string_number in &["1", "2", "three", "4"] {
  let number: u32 = match string_number.parse() {
    Ok(n) => n,
    Err(e) => continue,
  };
}

Then you can use the macro skip_error! to write like this.

for string_number in &["1", "2", "three", "4"] {
  let number: u32 = skip_error!(string_number.parse());
}

If you want the error to be logged, you can use the feature log. The logging will be done in WARN level with the standard logging interface provided by log.
