Struct EagerTestInstructionFetcher 

pub struct EagerTestInstructionFetcher { /* private fields */ }

Eager instruction handler eagerly decodes all instructions upfront

Implementations

impl EagerTestInstructionFetcher

pub unsafe fn new( instructions: Vec<ContractInstruction>, return_trap_address: u64, base_addr: u64, pc: u64, ) -> Self

Create a new instance with the specified instructions and base address.

Instructions are in the same order as they appear in the binary, and the base address corresponds to the first instruction.

return_trap_address is the address at which the interpreter will stop execution (gracefully).

Safety

The program counter must be valid and aligned, the instructions processed must end with a jump instruction.
