Struct miri::shims::env::EnvVars

source ·
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.
