Provided methods

pub fn valid_for(
    datatype: Option<Datatype>,
    format: &Option<String>
) -> Result<(), ValueError>

Check whether this value type is valid for the given property datatype and format string.

Returns Ok(()) if so, or Err(WrongFormat(...)) or Err(WrongDatatype(...)) if not.

The default implementation checks the datatype, and delegates to valid_for_format to check the format.

pub fn valid_for_format(_format: &str) -> Result<(), ValueError>

Check whether this value type is valid for the given property format string.

Returns Ok(()) if so, or Err(WrongFormat(...)) if not.
