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.

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.
