Struct strontium::machine::Strontium

pub struct Strontium {
    pub registers: Registers,
    pub ip: usize,
    pub call_stack: Vec<u8>,
    /* private fields */
}

Fields

registers: Registers

Holds general-purpose registers for storing different types of values

ip: usize

Points to the next index in the buffer of the bytecode register.

call_stack: Vec<u8>

Contains references for function arguments and return values

Implementations

impl Strontium

pub fn new() -> Self

Create a new instance of the virtual machine

pub fn push_bytecode(&mut self, bytes: Vec<u8>)

Append machine code to the array in the bytecode register.

pub fn execute( &mut self, instruction: Instruction ) -> Result<bool, StrontiumError>

Execute a single instruction.

pub fn consume_u64(&mut self) -> Result<u64, StrontiumError>

Consume an unsigned 64-bit integer from the bytecode register.

This performs a lookahead on the bytecode register to read the next eight bytes and converts the bytes into a 64-bit integer value. The byte encoding within Strontium bytecode is always Little Endian.

pub fn consume_u32(&mut self) -> Result<u32, StrontiumError>

pub fn consume_u16(&mut self) -> Result<u16, StrontiumError>

pub fn consume_u8(&mut self) -> Result<u8, StrontiumError>

pub fn consume_i64(&mut self) -> Result<i64, StrontiumError>

pub fn consume_i32(&mut self) -> Result<i32, StrontiumError>

pub fn consume_i16(&mut self) -> Result<i16, StrontiumError>

pub fn consume_i8(&mut self) -> Result<i8, StrontiumError>

pub fn consume_f64(&mut self) -> Result<f64, StrontiumError>

pub fn consume_f32(&mut self) -> Result<f32, StrontiumError>

pub fn consume_bool(&mut self) -> Result<bool, StrontiumError>

pub fn consume_byte(&mut self) -> Result<u8, StrontiumError>

pub fn consume_string(&mut self) -> Result<String, StrontiumError>
