⨍ Functions 239◇ Types & classes 58

↓ 35 callersMethodchild

Create and return a valid child header.

src/c2_blockchain/p3_consensus.rs:44

↓ 25 callersFunctionhash

Simple helper to do some hashing.

src/lib.rs:10

↓ 22 callersMethodchild

Create and return a valid child header. Without the extrinsics themselves, we cannot calculate the final state so that information is passed in.

src/c2_blockchain/p4_batched_extrinsics.rs:42

↓ 9 callersMethodchild

Create and return a valid child header.

src/c2_blockchain/p2_extrinsic_state.rs:38

↓ 8 callersMethodchild

Create and return a valid child header. The state root is passed in similarly to how the complete state was in the previous section.

src/c2_blockchain/p6_rich_state.rs:57

↓ 6 callersMethodchild

Create and return a valid child header.

src/c1_state_machine/p5_digital_cash.rs:53

↓ 1 callersFunctionbuild_an_invalid_chain

Build and return a chain with at least three headers. The chain should start with a proper genesis header, but the entire chain should NOT be valid.

src/c2_blockchain/p2_extrinsic_state.rs:72

↓ 1 callersFunctionbuild_an_invalid_chain

Build and return a chain with at least three headers. The chain should start with a proper genesis header, but the entire chain should NOT be valid.

Create an invalid child block of the given block. Although the child block is invalid, the header should be valid. Now that extrinsics are separate f

src/c2_blockchain/p4_batched_extrinsics.rs:109

↓ 1 callersFunctionbuild_invalid_child_block_with_valid_header

Create an invalid child block of the given block. The returned block should have an incorrect state root. Although the child block is invalid, the hea

src/c3_consensus/p4_even_only.rs:35

Methodauthor_and_import_automatic_block

Author a new block with the transactions from the pool on top of the "best" block and import the new block into the local database.

src/c4_client/p5_authoring_blocks.rs:19

Methodauthor_and_import_manual_block

Author a new block with the given transactions on top of the given parent and import the new block into the local database.
