46 /// Command for generating and sending an `engine_newPayload` request constructed from an RPC
47 /// block.
48 ///
49 /// This command takes a JSON block input (either from a file or stdin) and generates
50 /// an execution payload that can be used with the `engine_newPayloadV*` API.
51 ///
52 /// One powerful use case is pairing this command with the `cast block` command, for example:
53 ///
54 /// `cast block latest --full --json | reth-bench send-payload --rpc-url localhost:5000
55 /// --jwt-secret $(cat ~/.local/share/reth/mainnet/jwt.hex)`
56 SendPayload(send_payload::Command),
57
58 /// Generate a large block by packing transactions from existing blocks.
59 ///
60 /// This command fetches transactions from real blocks and packs them into a single
61 /// block using the `testing_buildBlockV1` RPC endpoint.
62 ///
63 /// Example:
64 ///
65 /// `reth-bench generate-big-block --rpc-url http://localhost:8545 --engine-rpc-url
66 /// http://localhost:8551 --jwt-secret ~/.local/share/reth/mainnet/jwt.hex --target-gas
67 /// 30000000`

71 ///
72 /// This command reads payload files from a previous `generate-big-block` run and replays
73 /// them in sequence using `newPayload` followed by `forkchoiceUpdated`.
74 ///
75 /// Example:
76 ///
77 /// `reth-bench replay-payloads --payload-dir ./payloads --engine-rpc-url
78 /// http://localhost:8551 --jwt-secret ~/.local/share/reth/mainnet/jwt.hex`

84 /// Engine API rejection behavior. Block hash is recalculated after modifications
85 /// unless `--invalid-block-hash` or `--skip-hash-recalc` is used.
86 ///
87 /// Example:
88 ///
89 /// `cast block latest --full --json | reth-bench send-invalid-payload --rpc-url localhost:5000
90 /// --jwt-secret $(cat ~/.local/share/reth/mainnet/jwt.hex) --invalid-state-root`
