Function RetrocausalQueueInsert 

pub fn RetrocausalQueueInsert(
    key: &StorageKeyContractData,
    queue_entry: &[u8],
) -> Result<(), SysErr>

Inserts an entry into the retrocausal queue at the specified storage key. Like any storage write, this replaces a value of another type at the key. A queue with no live entries does not exist.

Arguments

• key
• queue_entry

This is a convenience wrapper around uninit_RetrocausalQueueInsert that returns the result as SyscallResult<T>.

Errors

• kSyscallErrorCodeInvalidSyscallInput: The queue entry is too large, or too many entries are inserted in the current transaction.
