Trait probor::Decode

pub trait Decode: Sized {
    fn decode_elem<R: Input>(
        d: &mut Decoder<R>, 
        n: usize
    ) -> Result<Self, DecodeError>;
    fn decode_field<R: Input>(

    ) -> Result<Self, DecodeError>;
}

Required Methods

fn decode_elem<R: Input>(
    d: &mut Decoder<R>,
    n: usize
) -> Result<Self, DecodeError>

Decodes non-null array element and correctly propagates error.

The n is used only for errors

Propagating errors with try!(decode()) is dangerous as it may propagate UnexpectedNull in the middle of an array, which user may think it's just null. try!(decode_elem()) is safe

fn decode_field<R: Input>(
    d: &mut Decoder<R>,
    name: &'static str
) -> Result<Self, DecodeError>

Decodes non-null field and correctly propagates error.

The name is used only for errors

Propagating errors with try!(decode()) is dangerous as it may propagate UnexpectedNull in the middle of an array, which user may think it's just null. try!(decode_field()) is safe
