Enum stacking_iterator::Instruction
source · pub enum Instruction<T> {
Mutate(Operation<T>),
Yield,
}
Expand description
Control flow involving a stack.
Instructions are used to convert an iterator of Operation
s into an iterator of stack contents.
Variants§
Mutate(Operation<T>)
Mutate the stack with the given operation.
Yield
Yield the contents of the stack.
Implementations§
source§impl<T> Instruction<T>
impl<T> Instruction<T>
sourcepub const Pop: Instruction<T> = _
pub const Pop: Instruction<T> = _
sourcepub const fn Push(val: T) -> Instruction<T>
pub const fn Push(val: T) -> Instruction<T>
sourcepub fn into_operation(self) -> Option<Operation<T>>
pub fn into_operation(self) -> Option<Operation<T>>
Returns the operation, if mutating.
Examples
use stacking_iterator::prelude::*;
assert_eq!(Instruction::Push(1).into_operation(), Some(Operation::Push(1)));
assert_eq!(<Instruction<()>>::Pop.into_operation(), Some(Operation::Pop));
assert_eq!(<Instruction<()>>::Yield.into_operation(), None);
sourcepub fn as_operation(&self) -> Option<&Operation<T>>
pub fn as_operation(&self) -> Option<&Operation<T>>
Returns a reference to the operation, if mutating.
Examples
use stacking_iterator::prelude::*;
assert_eq!(Instruction::Push(1).as_operation(), Some(&Operation::Push(1)));
assert_eq!(<Instruction<()>>::Pop.as_operation(), Some(&Operation::Pop));
assert_eq!(<Instruction<()>>::Yield.as_operation(), None);
