Implementations

impl BlockReachability

pub fn join(&self, other: &BlockReachability) -> BlockReachability

Join two reachability values.

pub fn may_be_reachable(&self) -> bool

Return whether this block may be reachable.

Trait Implementations

impl Clone for BlockReachability

fn clone(&self) -> BlockReachability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockReachability

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

Formats the value using the given formatter.

impl PartialEq for BlockReachability

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