Struct InstructionTable

pub struct InstructionTable<T: Debug>(/* private fields */);

The instruction table.

Implemented as a HashMap behind the scenes.

Implementations

impl<T: Debug> InstructionTable<T>

pub fn new() -> InstructionTable<T>

Create a new empty instruction table.

pub fn by_op_code(&self, op_code: usize) -> Option<&Instruction<T>>

Retrieve an instruction by looking up it’s op code.

pub fn by_name(&self, name: &str) -> Option<&Instruction<T>>

Retrieve an instruction by looking up it’s name.

pub fn insert(&mut self, instr: Instruction<T>)

Insert an instruction into the table.

pub fn is_empty(&self) -> bool

Returns true if the instruction table is empty.

pub fn symbols(&self) -> Vec<(usize, String)>

Returns a list of symbols for use in the Code struct.

Generates a vector of tuples containing the op code and the name of each instruction.
