An individual standard virtual machine instruction.

Variants

CoreOp(CoreOp)

Execute a core instruction.

Set(Vec<f64>)

Set the register equal to a constant floating point value.

Alloc

Take the value of the register, and allocate that number of cells in memory. Set the register to the lowest address of the allocated memory.

Free

Free the memory pointed to by the register.

ToInt(usize)

Convert the register from a float to an integer.

ToFloat(usize)

Convert the register from an integer to a float.

Add(usize)

Add the value pointed to on the tape to the register (as floats).

Sub(usize)

Subtract the value pointed to on the tape from the register (as floats).

Mul(usize)

Multiply the register by the value pointed to on the tape (as floats).

Div(usize)

Divide the register by the value pointed to on the tape (as floats).

Rem(usize)

Store the remainder of the register and the value pointed to in the tape (as floats) into the register.

Neg(usize)

Negate the value of the register (as a float).

IsNonNegative(usize)

Make the register equal to the integer 1 if the register (as a float) is not negative, otherwise make it equal to 0.

Sin(usize)

Store the sine of the register (as a float) into the register. The argument is the size of the register vector.

Cos(usize)

Store the cosine of the register (as a float) into the register.

Tan(usize)

Store the tangent of the register (as a float) into the register.

ASin(usize)

Store the inverse-sine of the register (as a float) into the register.

ACos(usize)

Store the inverse-cosine of the register (as a float) into the register.

ATan(usize)

Store the inverse-tangent of the register (as a float) into the register.

Pow(usize)

Store the value of the register (as a float) to the power of the value pointed to on the tape (as a float) into the register.

Peek

Get a value from the input interface / device and store it in the register. This is intended to function something like system calls for using any external functionality that can’t be implemented in the virtual machine, such as I/O or OS operations.

Whenever a value is returned from the foreign function interface, it is stored in the FFI buffer of cells. Whenever an FFI function is called, it will receive its arguments from this buffer.

Poke

Write the value of the register to the output interface / device. This is intended to function something like system calls for using any external functionality that can’t be implemented in the virtual machine, such as I/O or OS operations.

Whenever a value is returned from the foreign function interface, it is stored in the FFI buffer of cells. Whenever an FFI function is called, it will receive its arguments from this buffer.

Call(FFIBinding)

Call a foreign function interface function.

Trait Implementations

impl Clone for StandardOp

fn clone(&self) -> StandardOp

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StandardOp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for StandardOp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for StandardOp

fn eq(&self, other: &StandardOp) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for StandardOp

fn partial_cmp(&self, other: &StandardOp) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
