Enum ScopeStackOp

pub enum ScopeStackOp {
    Push(Scope),
    Pop(usize),
    Clear(ClearAmount),
    Restore,
    Noop,
}

A change to a scope stack

Generally, Noop is only used internally and you won’t need to worry about getting one back from calling a public function.

The change from a ScopeStackOp can be applied via ScopeStack::apply.

Variants

Push(Scope)

Pop(usize)

Clear(ClearAmount)

Used for the clear_scopes feature

Restore

Restores cleared scopes

Noop

Trait Implementations

impl Clone for ScopeStackOp

fn clone(&self) -> ScopeStackOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScopeStackOp

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

Formats the value using the given formatter.

impl PartialEq for ScopeStackOp

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

Tests for self and other values to be equal, and is used by ==.

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

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