Instruction.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PushConst(Value)

Push constant.

PushValue(CExpPtr<Value>)

Push expression.

PushLocal(usize)

Push local variable.

PopToLocal(usize)

Assign local variable.

Jump(usize)

Jump.

JumpIfFalse(usize, CExpPtr<bool>)

Jump if false.

Call(Rc<Function>)

Call

Return

Return from function.

Throw

Throw error.

Execute

Execute string.

ForInit(usize, Box<CTableExpression>)

Initialise FOR statement.

ForNext(usize, Box<ForNextInfo>)

Next iteration of FOR statement.

ForSortInit(usize, Box<CFromExpression>)

Initialise FOR statement ( sorted case ).

ForSortNext(usize, Box<(usize, usize, Assigns)>)

Next iteration of FOR statement ( sorted case ).

DataOp(Box<DO>)

Data operation.

Select(Box<CFromExpression>)

SELECT expression.

Set(Box<CFromExpression>)

Set local variables from table.

PushInt(CExpPtr<i64>)

Push Integer expression.

PushFloat(CExpPtr<f64>)

Push Float expression.

PushBool(CExpPtr<bool>)

Push bool expression.

AssignLocal(usize, CExpPtr<Value>)

Assign a local variable.

AppendLocal(usize, CExpPtr<Value>)

Append to a local variable.

IncLocal(usize, CExpPtr<Value>)

Increment (+=) a local variable.

DecLocal(usize, CExpPtr<Value>)

Decrement (-=) a local variable.
