Enum EnvHandle 

#[non_exhaustive]
pub enum EnvHandle {
    Global,
    Base,
    Empty,
    Other,
}

An opaque handle to an environment.

rd-rds never models environment frames or enclosures: it only consumes the wire bytes correctly and keeps the reference table aligned. All non-singleton environments collapse to EnvHandle::Other.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Global

R_GlobalEnv.

Base

R_BaseEnv / R_BaseNamespace.

Empty

R_EmptyEnv.

Other

Any other environment/package/namespace. Its wire fields were decoded (to keep the stream and reference table in sync) and then discarded.
