pub struct ValidTransactionBuilder { /* private fields */ }
Expand description

ValidTransaction builder.

Allows to easily construct ValidTransaction and most importantly takes care of prefixing requires and provides tags to avoid conflicts.

Implementations

Set the priority of a transaction.

Note that the final priority for FRAME is combined from all SignedExtensions. Most likely for unsigned transactions you want the priority to be higher than for regular transactions. We recommend exposing a base priority for unsigned transactions as a runtime module parameter, so that the runtime can tune inter-module priorities.

Set the longevity of a transaction.

By default the transaction will be considered valid forever and will not be revalidated by the transaction pool. It’s recommended though to set the longevity to a finite value though. If unsure, it’s also reasonable to expose this parameter via module configuration and let the runtime decide.

Set the propagate flag.

Set to false if the transaction is not meant to be gossiped to peers. Combined with TransactionSource::Local validation it can be used to have special kind of transactions that are only produced and included by the validator nodes.

Add a TransactionTag to the set of required tags.

The tag will be encoded and prefixed with module prefix (if any). If you’d rather add a raw require tag, consider using #combine_with method.

Add a TransactionTag to the set of provided tags.

The tag will be encoded and prefixed with module prefix (if any). If you’d rather add a raw require tag, consider using #combine_with method.

Augment the builder with existing ValidTransaction.

This method does add the prefix to require or provides tags.

Finalize the builder and produce TransactionValidity.

Note the result will always be Ok. Use Into to produce ValidTransaction.
