Struct miri::EnvVars

pub struct EnvVars<'tcx> {
    map: FxHashMap<OsString, Pointer<Option<Provenance>>>,
    pub(crate) environ: Option<MPlaceTy<'tcx, Provenance>>,
}

Fields

map: FxHashMap<OsString, Pointer<Option<Provenance>>>

Stores pointers to the environment variables. These variables must be stored as null-terminated target strings (c_str or wide_str) with the "{name}={value}" format.

environ: Option<MPlaceTy<'tcx, Provenance>>

Place where the environ static is stored. Lazily initialized, but then never changes.

Implementations

impl<'tcx> EnvVars<'tcx>

pub(crate) fn init<'mir>(
    ecx: &mut InterpCx<'mir, 'tcx, MiriMachine<'mir, 'tcx>>,
    config: &MiriConfig
) -> InterpResult<'tcx>

pub(crate) fn cleanup<'mir>(
    ecx: &mut InterpCx<'mir, 'tcx, MiriMachine<'mir, 'tcx>>
) -> InterpResult<'tcx>

Trait Implementations

impl<'tcx> Default for EnvVars<'tcx>

fn default() -> EnvVars<'tcx>

Returns the “default value” for a type.

impl VisitTags for EnvVars<'_>

fn visit_tags(&self, visit: &mut dyn FnMut(BorTag))

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.
