Trait Implementations§

source§

impl Visitor for IgnoreVisitor

§

type Value<'scale, 'info> = ()

The type of the value to hand back from the decode_with_visitor() function.
§

type Error = DecodeError

The error type (which we must be able to convert a combination of Self and DecodeErrors into, to handle any internal errors that crop up trying to decode things).
source§

fn visit_unexpected<'scale, 'info>( self, _unexpected: Unexpected ) -> Result<Self::Value<'scale, 'info>, Self::Error>

This is called when a visitor function that you’ve not provided an implementation is called. You are provided an enum value corresponding to the function call, and can decide what to return in this case. The default is to return an error to announce the unexpected value.
source§

fn unchecked_decode_as_type<'scale, 'info>( self, _input: &mut &'scale [u8], _type_id: TypeId, _types: &'info PortableRegistry ) -> DecodeAsTypeResult<Self, Result<Self::Value<'scale, 'info>, Self::Error>>

This method is called immediately upon running decode_with_visitor(). By default we ignore this call and return our visitor back (ie [DecodeAsTypeResult::Skipped(visitor)]). If you choose to do some decoding at this stage, return [DecodeAsTypeResult::Decoded(result)]. In either case, any bytes that you consume from the input (by altering what it points to) will be consumed for any subsequent visiting. Read more
