§Returns
  • PropResult - The new PropResult.
Source

pub fn to_result(self) -> Result<String>

The to_result method can convert the PropResult to Result.
to_resultメソッドはPropResultをResultに変換することができる.

§Returns
  • Result<String> - The result of the PropResult.
Source

pub fn to_result_unit(self) -> Result<()>
