/// Checks whether the standard library's panic hook will capture and print a
/// backtrace.
/// 
/// This function will, if a backtrace style has not been set via
/// [`set_backtrace_style`], read the environment variable `RUST_BACKTRACE` to
/// determine a default value for the backtrace formatting:
/// 
/// The first call to `get_backtrace_style` may read the `RUST_BACKTRACE`
/// environment variable if `set_backtrace_style` has not been called to
/// override the default value. After a call to `set_backtrace_style` or
/// `get_backtrace_style`, any changes to `RUST_BACKTRACE` will have no effect.
/// 
/// `RUST_BACKTRACE` is read according to these rules:
/// 
/// * `0` for `BacktraceStyle::Off`
/// * `full` for `BacktraceStyle::Full`
/// * `1` for `BacktraceStyle::Short`
/// * Other values are currently `BacktraceStyle::Short`, but this may change in
///   the future
/// 
/// Returns `None` if backtraces aren't currently supported.
