Trait TestBlock

pub trait TestBlock: Block<Header: TestHeader> {
    // Required methods
    fn body_mut(&mut self) -> &mut Self::Body;
    fn header_mut(&mut self) -> &mut Self::Header;
    fn set_header(&mut self, header: Self::Header);

    // Provided methods
    fn set_parent_hash(&mut self, hash: BlockHash) { ... }
    fn set_block_number(&mut self, number: BlockNumber) { ... }
    fn set_state_root(&mut self, state_root: B256) { ... }
    fn set_difficulty(&mut self, difficulty: U256) { ... }
}

Available on crate feature test-utils only.

An extension trait for Blocks that allows for mutable access to the block’s internals.

This allows for modifying the block’s header and body for testing purposes.

Required Methods

fn body_mut(&mut self) -> &mut Self::Body

Returns mutable reference to block body.

fn header_mut(&mut self) -> &mut Self::Header

Returns mutable reference to block header.

fn set_header(&mut self, header: Self::Header)

Updates the block header.

Provided Methods

fn set_parent_hash(&mut self, hash: BlockHash)

Updates the parent block hash.

fn set_block_number(&mut self, number: BlockNumber)

Updates the block number.

fn set_state_root(&mut self, state_root: B256)

Updates the block state root.

fn set_difficulty(&mut self, difficulty: U256)

Updates the block difficulty.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
