Module scale_decode::visitor

The Visitor trait and associated types.

Modules

• types
  Types used in the super::Visitor trait definition.

Structs

• IgnoreVisitor
  A Visitor implementation that just ignores all of the bytes.
• TypeId
  The ID of the type being decoded.
• VisitorWithCrateError
  Some Visitor implementations may want to return an error type other than crate::Error, which means that they would not be automatically compatible with crate::IntoVisitor, which requires visitors that do return crate::Error errors.

Enums

• DecodeAsTypeResult
  The response from Visitor::unchecked_decode_as_type().
• DecodeError
  An error decoding SCALE bytes.
• Unexpected
  This is returned by default when a visitor function isn’t implemented.

Traits

• DecodeItemIterator
  This is implemented for visitor related types which have a decode_item method, and allows you to generically talk about decoding unnamed items.
• Visitor
  An implementation of the Visitor trait can be passed to the decode_with_visitor() function, and is handed back values as they are encountered. It’s up to the implementation to decide what to do with these values.

Functions

• decode_with_visitor
  Decode data according to the type ID and PortableRegistry provided. The provided pointer to the data slice will be moved forwards as needed depending on what was decoded, and a method on the provided Visitor will be called depending on the type that needs to be decoded.

Type Aliases

• BitSequenceError
  An error that can occur trying to decode a bit sequence.
