Contract
- assert anyhow captures backtraces with status Captured when RUST_BACKTRACE is enabled
- assert anyhow backtrace status is Disabled when RUST_BACKTRACE is zero or unset
- assert RUST_LIB_BACKTRACE=0 overrides RUST_BACKTRACE=1 to disable anyhow backtrace capture
- assert RUST_LIB_BACKTRACE=1 overrides RUST_BACKTRACE=0 to enable anyhow backtrace capture
- assert anyhow backtrace capture is eager at instantiation time and does not capture retroactively when env changes
- assert Debug formatting appends Stack backtrace only when backtrace status is Captured
- assert Display and Alternate Display format error messages and chains without backtrace frames
- assert anyhow::Error::backtrace provides an inherent method returning a reference to std Backtrace
