Trait attribution::FromParameters

pub trait FromParameters: Sized {
    fn from_parameters<'a>(
        params: &mut Parameters, 
        param_key: &'a ParamKey
    ) -> Result<Self, FromParametersError<'a>>;
}

A trait that is used to extract data from a Parameters struct.

Required methods

fn from_parameters<'a>(
    params: &mut Parameters,
    param_key: &'a ParamKey
) -> Result<Self, FromParametersError<'a>>

Try to create a type from a parameter struct (params) for a paramter of a specific name (param_name).
