Trait TestHeader

pub trait TestHeader: BlockHeader {
    // Required methods
    fn set_parent_hash(&mut self, hash: FixedBytes<32>);
    fn set_block_number(&mut self, number: u64);
    fn set_state_root(&mut self, state_root: FixedBytes<32>);
    fn set_difficulty(&mut self, difficulty: Uint<256, 4>);
}

Available on crate features test-utils or arbitrary only.

A helper trait for Headers that allows for mutable access to the headers values.

This allows for modifying the header for testing purposes.

Required Methods

fn set_parent_hash(&mut self, hash: FixedBytes<32>)

Updates the parent block hash.

fn set_block_number(&mut self, number: u64)

Updates the block number.

fn set_state_root(&mut self, state_root: FixedBytes<32>)

Updates the block state root.

fn set_difficulty(&mut self, difficulty: Uint<256, 4>)

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.
