Struct brane_exe::stack::StackSlice

pub struct StackSlice { /* private fields */ }

Represents a slice of the Stack.

Implementations

impl StackSlice

pub fn peek(&self) -> Option<&Value>

Returns the top value of the stack without popping it.

Returns

The top value of the stack, or None if the stack (slice) is empty.

pub fn len(&self) -> usize

The number of elements in this slice.

pub fn is_empty(&self) -> bool

Returns whether this slice is empty or not (i.e., has zero-length)

pub fn iter(&mut self) -> impl Iterator<Item = &Value>

Returns a reference-iterator for the slice.

pub fn iter_mut(&mut self) -> impl Iterator<Item = &mut Value>

Returns a muteable reference-iterator for the slice.
