Trait BlockHandler 

pub trait BlockHandler {
    // Required methods
    fn get_block_number(&self, snapshot_id: usize) -> Result<DynSolValue>;
    fn get_block_timestamp(&self, snapshot_id: usize) -> Result<DynSolValue>;
}

Handler trait for block global variables.

Provides access to blockchain context like block number and timestamp.

Required Methods

fn get_block_number(&self, snapshot_id: usize) -> Result<DynSolValue>

Get the current block number (block.number).

Arguments

• snapshot_id - The execution context identifier

Returns

The block number as a DynSolValue::Uint

fn get_block_timestamp(&self, snapshot_id: usize) -> Result<DynSolValue>

Get the current block timestamp (block.timestamp).

Arguments

• snapshot_id - The execution context identifier

Returns

The block timestamp as a DynSolValue::Uint
