}Expand description
core
Inspects an environment variable at compile time.
Re-exported from core::env.
The reason of the _ suffix is to avoid conflicting with Rust’s prelude
when glob importing from this crate. Since this macro has the same name
as its sibling module core::env, in order to be able to re-export
only the macro we have to wrap it with our own.
