Enum DecoratorStore 

pub enum DecoratorStore {
    Owned {
        decorators: DecoratorList,
        before_enter: Vec<DecoratorId>,
        after_exit: Vec<DecoratorId>,
    },
    Linked {
        id: MastNodeId,
    },
}

A data structure for storing decorators for MAST nodes, including both operation-level decorators and node-level decorators (before_enter/after_exit).

Variants

Owned

The decorators are owned by this node. This is the case for nodes which have not yet been inserted into a MAST forest.

Fields

decorators: DecoratorList

Operation-level decorators indexed by operation position (Note: Only used by BasicBlockNode, other nodes will have empty decorators)

before_enter: Vec<DecoratorId>

Node-level decorators executed before entering the node

after_exit: Vec<DecoratorId>

Node-level decorators executed after exiting the node

Linked

The decorators are stored in a MAST forest and can be accessed via this node’s ID. All decorator reads borrow from the forest’s storage.

Fields

id: MastNodeId

Implementations

impl DecoratorStore

pub fn new_owned_with_decorators( before_enter: Vec<DecoratorId>, after_exit: Vec<DecoratorId>, ) -> Self

Create a new Owned decorator store with the specified before/after decorators

pub fn before_enter<'a>(&'a self, forest: &'a MastForest) -> &'a [DecoratorId]

Get the before_enter decorators, borrowing from the forest if linked

pub fn after_exit<'a>(&'a self, forest: &'a MastForest) -> &'a [DecoratorId]

Get the after_exit decorators, borrowing from the forest if linked

pub fn is_linked(&self) -> bool

Check if this store is in the Linked state

pub fn linked_id(&self) -> Option<MastNodeId>

Get the node ID if this store is in the Linked state

Trait Implementations

impl Clone for DecoratorStore

fn clone(&self) -> DecoratorStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecoratorStore

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

Formats the value using the given formatter.

impl Default for DecoratorStore

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DecoratorStore

fn eq(&self, other: &DecoratorStore) -> 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.
