Trait Implementations

impl Clone for BasicBlock

fn clone(&self) -> BasicBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BasicBlock

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

Formats the value using the given formatter.

impl DirectedGraphNode for BasicBlock

fn index(&self) -> usize

fn predecessors(&self) -> &HashSet<usize>

fn successors(&self) -> &HashSet<usize>

impl VariableMeta for BasicBlock

fn cache_variable_use(&mut self)

Compute variables read/written by the node. Must be called before either of the getters are called. To avoid interior mutability this needs to be called again whenever the node is mutated in a way that may invalidate the cached variable use.

fn locals_read(&self) -> &VariableUses

Get the set of variables read by the IR node.

fn locals_written(&self) -> &VariableUses

Get the set of variables written by the IR node.

fn signals_read(&self) -> &VariableUses

Get the set of signals read by the IR node. Note that this does not include signals belonging to sub-components.

fn signals_written(&self) -> &VariableUses

Get the set of signals written by the IR node. Note that this does not include signals belonging to sub-components.

fn components_read(&self) -> &VariableUses

Get the set of components read by the IR node. Note that a component read is typically a signal read for a signal exported by the component.

fn components_written(&self) -> &VariableUses

Get the set of components written by the IR node. Note that a component write may either be a component initialization, or a signal write for a signal exported by the component.

fn variables_read<'a>( &'a self, ) -> Box<dyn Iterator<Item = &'a VariableUse> + 'a>

Get the set of variables read by the IR node. Note that this is simply the union of all locals, signals, and components read by the node.

fn variables_written<'a>( &'a self, ) -> Box<dyn Iterator<Item = &'a VariableUse> + 'a>

Get the set of variables written by the IR node. Note that this is simply the union of all locals, signals, and components written.

fn variables_used<'a>( &'a self, ) -> Box<dyn Iterator<Item = &'a VariableUse> + 'a>

Get the set of variables either read or written by the IR node.
