Struct MachineStack 

pub struct MachineStack(/* private fields */);

An implementation of Stack.

Implementations

impl MachineStack

pub const fn new() -> Self

Creates an empty stack.

pub fn len(&self) -> usize

Returns the number of values in the stack.

pub fn is_empty(&self) -> bool

Reports whether the stack is empty.

pub fn into_vec(self) -> Vec<Value>

Turn a Stack into a Vec of Values.

Trait Implementations

impl Default for MachineStack

fn default() -> Self

Returns the “default value” for a type.

impl Stack for MachineStack

fn push_value(&mut self, value: Value) -> Result<(), MachineErrorType>

Push a value (as a Value) onto the stack.

fn pop_value(&mut self) -> Result<Value, MachineErrorType>

Pop a value (as a Value) from the stack.

fn peek_value(&mut self) -> Result<&mut Value, MachineErrorType>

Peek a value (as a mutable reference to a Value) on the top of the stack.

fn push<V>(&mut self, value: V) -> Result<(), MachineErrorType>

where V: Into<Value>,

Push a value onto the stack.

fn pop<V>(&mut self) -> Result<V, MachineErrorType>

where V: TryFromValue,

Pop a value off of the stack.

fn peek<V>(&mut self) -> Result<&mut V, MachineErrorType>

where V: ?Sized, Value: TryAsMut<V, Error = ValueConversionError>,

Get a reference to the value at the top of the stack
