Enum muse_lang::runtime::value::ContextOrGuard

pub enum ContextOrGuard<'a, 'context, 'guard> {
    Guard(&'a CollectionGuard<'guard>),
    Context(&'a mut VmContext<'context, 'guard>),
}

A reference to a [CollectionGuard] or a VmContext.

This type is used when a function may need to be invoked with or without a VmContext.

Variants

Guard(&'a CollectionGuard<'guard>)

A collection guard.

Context(&'a mut VmContext<'context, 'guard>)

An execution context.

Implementations

impl<'a, 'context, 'guard> ContextOrGuard<'a, 'context, 'guard>

pub fn vm(&mut self) -> Option<&mut VmContext<'context, 'guard>>

Returns a reference to the execution context, if available.

pub fn borrowed(&mut self) -> ContextOrGuard<'_, 'context, 'guard>

Returns a new ContextOrGuard that borrows from self.

Trait Implementations

impl<'context, 'guard> AsRef<CollectionGuard<'guard>> for ContextOrGuard<'_, 'context, 'guard>

fn as_ref(&self) -> &CollectionGuard<'guard>

Converts this type into a shared reference of the (usually inferred) input type.
