Struct rustc_const_eval::transform::check_consts::ConstCx

pub struct ConstCx<'mir, 'tcx> {
    pub body: &'mir Body<'tcx>,
    pub tcx: TyCtxt<'tcx>,
    pub param_env: ParamEnv<'tcx>,
    pub const_kind: Option<ConstContext>,
}

Information about the item currently being const-checked, as well as a reference to the global context.

Fields

body: &'mir Body<'tcx>

tcx: TyCtxt<'tcx>

param_env: ParamEnv<'tcx>

const_kind: Option<ConstContext>

Implementations

impl<'mir, 'tcx> ConstCx<'mir, 'tcx>

pub fn new(tcx: TyCtxt<'tcx>, body: &'mir Body<'tcx>) -> Self

pub fn new_with_param_env(
    tcx: TyCtxt<'tcx>,
    body: &'mir Body<'tcx>,
    param_env: ParamEnv<'tcx>
) -> Self

pub fn def_id(&self) -> LocalDefId

pub fn const_kind(&self) -> ConstContext

Returns the kind of const context this Item represents (const, static, etc.).

Panics if this Item is not const.

pub fn is_const_stable_const_fn(&self) -> bool

pub fn fn_sig(&self) -> Option<&'tcx FnSig<'tcx>>

Returns the function signature of the item being const-checked if it is a fn or const fn.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
