Macro build_helper::t

macro_rules! t {
    ($e:expr) => { ... };
}

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

A helper macro to unwrap a result except also print out details like:

• The file/line of the panic
• The expression that failed
• The error itself

This is currently used judiciously throughout the build system rather than using a Result with try!, but this may change one day...
