Struct EthInstructions 

pub struct EthInstructions<WIRE, HOST>
where
    WIRE: InterpreterTypes,
    HOST: ?Sized,
{
    pub spec: SpecId,
    /* private fields */
}

Ethereum instruction contains list of mainnet instructions that is used for Interpreter execution.

Fields

spec: SpecId

Spec that is used to set gas costs for instructions.

Implementations

impl<WIRE, HOST> EthInstructions<WIRE, HOST>

where WIRE: InterpreterTypes, HOST: Host,

pub fn new_mainnet() -> EthInstructions<WIRE, HOST>

👎Deprecated since 0.2.0:

use new_mainnet_with_spec instead

Returns EthInstructions with mainnet spec.

pub fn new_mainnet_with_spec(spec: SpecId) -> EthInstructions<WIRE, HOST>

Returns EthInstructions with mainnet spec.

pub fn new( instruction_table: [Instruction<WIRE, HOST>; 256], gas_table: [u16; 256], spec: SpecId, ) -> EthInstructions<WIRE, HOST>

Returns a new instance of EthInstructions with custom instruction and gas tables.

pub fn insert_instruction( &mut self, opcode: u8, instruction: Instruction<WIRE, HOST>, gas: u16, )

Inserts a new instruction into the instruction table.

pub fn insert_gas(&mut self, opcode: u8, gas: u16)

Inserts a new gas cost into the gas table.

pub fn instruction_table(&self) -> &[Instruction<WIRE, HOST>; 256]

Returns a reference to the instruction table.

pub fn instruction_table_mut(&mut self) -> &mut [Instruction<WIRE, HOST>; 256]

Returns a mutable reference to the instruction table.

pub fn gas_table(&self) -> &[u16; 256]

Returns a reference to the gas table.

pub fn gas_table_mut(&mut self) -> &mut [u16; 256]

Returns a mutable reference to the gas table.

fn gas_table(&self) -> &[u16; 256]

Returns the gas table for static gas costs.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
