Implementations

impl CEP95ReceiverHostRef

pub fn on_cep95_received( &mut self, operator: &Address, from: &Address, token_id: &U256, data: &Option<Bytes>, ) -> bool

Called after a safe_transfer_from completes its internal state update. MUST return true to signal acceptance; returning false or reverting causes the entire transfer to roll back.

Arguments

operator - The account (EOA or contract) that invoked safe_transfer_from. from - The previous owner of token_id. token_id - The NFT being transferred. data - Opaque auxiliary data forwarded from the original call; may be None if no extra data was supplied.

Returns

true to accept the NFT, anything else to reject.
