Struct pallet_messages::pallet::Pallet

impl<T: Config> Pallet<T>

pub fn add_ipfs_message( origin: OriginFor<T>, schema_id: SchemaId, cid: Vec<u8>, payload_length: u32 ) -> DispatchResult

Adds a message for a resource hosted on IPFS. The input consists of both a Base32-encoded CID as well as a 32-bit content length. The stored payload will contain the CID encoded as binary, as well as the 32-bit message content length. The actual message content will be on IPFS.

Events

Event::MessagesInBlock - Messages Stored in the block

Errors

Error::ExceedsMaxMessagePayloadSizeBytes - Payload is too large
Error::InvalidSchemaId - Schema not found
Error::InvalidPayloadLocation - The schema is not an IPFS payload location
Error::InvalidMessageSourceAccount - Origin must be from an MSA
Error::TypeConversionOverflow - Failed to add the message to storage as it is very full
Error::UnsupportedCidVersion - CID version is not supported (V0)
Error::InvalidCid - Unable to parse provided CID

pub fn add_onchain_message( origin: OriginFor<T>, on_behalf_of: Option<MessageSourceId>, schema_id: SchemaId, payload: Vec<u8> ) -> DispatchResult

Add an on-chain message for a given schema id.

Events

Event::MessagesInBlock - In the next block

Errors

Error::ExceedsMaxMessagePayloadSizeBytes - Payload is too large
Error::InvalidSchemaId - Schema not found
Error::InvalidPayloadLocation - The schema is not an IPFS payload location
Error::InvalidMessageSourceAccount - Origin must be from an MSA
Error::UnAuthorizedDelegate - Trying to add a message without a proper delegation between the origin and the on_behalf_of MSA
Error::TypeConversionOverflow - Failed to add the message to storage as it is very full

impl<T: Config> Pallet<T>

pub fn add_message( provider_msa_id: MessageSourceId, msa_id: Option<MessageSourceId>, payload: BoundedVec<u8, T::MessagesMaxPayloadSizeBytes>, schema_id: SchemaId, current_block: BlockNumberFor<T> ) -> Result<bool, DispatchError>

Errors

Error::TypeConversionOverflow

Payload location is included to map to correct response (To avoid fetching the schema in this method)

Result is a vector of [MessageResponse].

pub fn validate_cid(in_cid: &Vec<u8>) -> Result<Vec<u8>, DispatchError>

Validates a CID to conform to IPFS CIDv1 (or higher) formatting (does not validate decoded CID fields)

Errors
