Struct gf::pivot::fragment::FragmentDefsUses

pub struct FragmentDefsUses<'a> { /* fields omitted */ }

🟢 Defined and used variables of a sealed fragment.

Definitions and uses are prebuilt for all sealed fragments, and can be retrieved via Fragment::defs_uses.

Implementations

impl<'a> FragmentDefsUses<'a>

pub unsafe fn from_unsealed(
    fragment: Fragment<'a>,
    unsealed: &'a UnsealedFragmentDefsUses
) -> Self

Wrap an unsealed defined and used variable structure.

pub fn fragment(&self) -> Fragment<'a>

Return parent fragment.

pub fn vars(&self) -> &'a [Var]

Return all variables defined and/or used in the fragment in increasing order of their numbers.

pub fn def(&self, var: Var) -> Option<Loc<'a>>

Return variable definition.

Tail locations correspond to inputs of basic blocks.

pub fn uses(&self, var: Var) -> impl Iterator<Item = Loc<'a>> + '_

Return an iterator over variable uses.

Tail locations correspond to outputs of basic blocks.

impl<'a> Clone for FragmentDefsUses<'a>

fn clone(&self) -> FragmentDefsUses<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.
