Struct EnvOps 

pub struct EnvOps;

EnvOps

NOTE:

• try_* getters are test-only helpers for incomplete env setup.
• Non-try_* getters assume the environment has been fully initialized during canister startup and will panic if called earlier.
• After initialization, absence of environment fields is a programmer error.
