Enum InstructionTables

pub enum InstructionTables<W: InterpreterTypes, H: ?Sized, CI: CustomInstruction<Host = H, Wire = W>> {
    Plain(Box<InstructionTable<W, H>>),
    Custom(Box<CustomInstructionTable<CI>>),
}

Either a plain, static instruction table, or a boxed, dynamic instruction table.

Note that Plain variant is about 10-20% faster in Interpreter execution.

Variants

Plain(Box<InstructionTable<W, H>>)

Custom(Box<CustomInstructionTable<CI>>)

Implementations

impl<WIRE, H, CI> InstructionTables<WIRE, H, CI>

where WIRE: InterpreterTypes, H: Host + ?Sized, CI: CustomInstruction<Host = H, Wire = WIRE>,

pub fn insert(&mut self, opcode: u8, instruction: Instruction<WIRE, H>)

Inserts the instruction into the table with the specified index.

pub fn to_custom(&mut self) -> &mut CustomInstructionTable<CI>

Converts the current instruction table to a boxed variant if it is not already, and returns a mutable reference to the boxed table.

pub fn to_custom_with<F>(&mut self, f: F) -> &mut CustomInstructionTable<CI>

where F: FnMut(Instruction<WIRE, H>) -> CI,

Converts the current instruction table to a boxed variant if it is not already with f, and returns a mutable reference to the boxed table.

pub fn get_custom(&mut self, opcode: u8) -> &mut CI

Returns a mutable reference to the boxed instruction at the specified index.

pub fn insert_custom(&mut self, opcode: u8, instruction: CI)

Inserts a boxed instruction into the table at the specified index.

pub fn replace_boxed(&mut self, opcode: u8, instruction: CI) -> CI

Replaces a boxed instruction into the table at the specified index, returning the previous instruction.
