Implementations

impl<'a> SwitchOp<'a>

pub fn branches(&self) -> impl Iterator<Item = Region<'a>>

Returns an iterator over the branches of this switch statement.

pub fn branch_count(&self) -> usize

Returns the number of branches in this switch statement.

pub fn branch(&self, n: usize) -> Region<'a>
