Struct ValidationPlainMessageProcessor

pub struct ValidationPlainMessageProcessor;

A message processor that validates messages

This processor validates incoming and outgoing DIDComm messages to ensure they conform to the expected structure and protocol requirements.

In a production implementation, this would perform comprehensive validation including:

• Field validation (required fields, format, values)
• Protocol compliance checks for each message type
• Signature verification
• Timestamp and expiration checks
• Security and authorization checks

Implementation

Currently, this implementation validates:

• The message ID is not empty
• The message type is not empty
• Any ‘from’ or ‘to’ DIDs follow the ‘did:’ prefix format
• Basic protocol-specific requirements based on message type

PlainMessage Flow

The validator sits in the message processor pipeline and can filter out invalid messages by returning Ok(None), or let valid messages continue through the pipeline by returning Ok(Some(message)).
