pub enum Transaction {
    UserTransaction(SignedTransaction),
    GenesisTransaction(WriteSetPayload),
    BlockMetadata(BlockMetadata),
}
Expand description

Transaction will be the transaction type used internally in the diem node to represent the transaction to be processed and persisted.

We suppress the clippy warning here as we would expect most of the transaction to be user transaction.

Variants§

§

UserTransaction(SignedTransaction)

Transaction submitted by the user. e.g: P2P payment transaction, publishing module transaction, etc. TODO: We need to rename SignedTransaction to SignedUserTransaction, as well as all the other transaction types we had in our codebase.

§

GenesisTransaction(WriteSetPayload)

Transaction that applies a WriteSet to the current storage, it’s applied manually via db-bootstrapper.

§

BlockMetadata(BlockMetadata)

Transaction to update the block metadata resource at the beginning of a block.

Trait Implementations§

source§

impl Arbitrary for Transaction

§

type Parameters = (<SignedTransaction as Arbitrary>::Parameters, <WriteSetPayload as Arbitrary>::Parameters, <BlockMetadata as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.
§

type Strategy = TupleUnion<((u32, Arc<Map<<SignedTransaction as Arbitrary>::Strategy, fn(_: SignedTransaction) -> Transaction>>), (u32, Arc<Map<<WriteSetPayload as Arbitrary>::Strategy, fn(_: WriteSetPayload) -> Transaction>>), (u32, Arc<Map<<BlockMetadata as Arbitrary>::Strategy, fn(_: BlockMetadata) -> Transaction>>))>

The type of Strategy used to generate values of type Self.
source§

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args. Read more
