Struct rustc::middle::subst::Substs[src]

pub struct Substs {
    pub types: VecPerParamSpace<t>,
    pub regions: RegionSubsts,
}

A substitution mapping type/region parameters to new values. We identify each in-scope parameter by an index and a parameter space (which indices where the parameter is defined; see ParamSpace).

Methods

impl Substs

fn new(t: VecPerParamSpace<t>, r: VecPerParamSpace<Region>) -> Substs

fn new_type(t: Vec<t>, r: Vec<Region>) -> Substs

fn new_trait(t: Vec<t>, r: Vec<Region>, s: t) -> Substs

fn erased(t: VecPerParamSpace<t>) -> Substs

fn empty() -> Substs

fn trans_empty() -> Substs

fn is_noop(&self) -> bool

fn self_ty(&self) -> Option<t>

fn with_self_ty(&self, self_ty: t) -> Substs

fn regions<'a>(&'a self) -> &'a VecPerParamSpace<Region>

Since ErasedRegions are only to be used in trans, most of the compiler can use this method to easily access the set of region substitutions.

fn mut_regions<'a>(&'a mut self) -> &'a mut VecPerParamSpace<Region>

Since ErasedRegions are only to be used in trans, most of the compiler can use this method to easily access the set of region substitutions.

fn with_method_from(self, substs: &Substs) -> Substs

fn with_method(self, m_types: Vec<t>, m_regions: Vec<Region>) -> Substs
