Struct miri::shims::unix::env::UnixEnvVars

pub struct UnixEnvVars<'tcx> {
    map: FxHashMap<OsString, Pointer<Option<Provenance>>>,
    environ: 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: MPlaceTy<'tcx, Provenance>

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

Implementations

impl<'tcx> UnixEnvVars<'tcx>

pub(crate) fn new<'mir>( ecx: &mut InterpCx<'mir, 'tcx, MiriMachine<'mir, 'tcx>>, env_vars: FxHashMap<OsString, OsString> ) -> InterpResult<'tcx, Self>

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

pub(crate) fn environ(&self) -> Pointer<Option<Provenance>>

fn get_ptr<'mir>( &self, ecx: &InterpCx<'mir, 'tcx, MiriMachine<'mir, 'tcx>>, name: &OsStr ) -> InterpResult<'tcx, Option<Pointer<Option<Provenance>>>>

pub(crate) fn get<'mir>( &self, ecx: &InterpCx<'mir, 'tcx, MiriMachine<'mir, 'tcx>>, name: &OsStr ) -> InterpResult<'tcx, Option<OsString>>

Implementation detail for InterpCx::get_env_var. This basically does getenv, complete with the reads of the environment, but returns an OsString instead of a pointer.

Trait Implementations

impl VisitProvenance for UnixEnvVars<'_>

fn visit_provenance(&self, visit: &mut VisitWith<'_>)

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.
