Struct better_panic::Settings

pub struct Settings { /* private fields */ }

Configuration for panic printing.

Implementations

impl Settings

pub fn new() -> Self

Alias for Settings::default.

pub fn debug() -> Self

Common settings for debugging.

pub fn auto() -> Self

In release builds this is new, in debug builds this is debug.

pub fn message(self, message: impl Into<String>) -> Self

Controls the “greeting” message of the panic.

Defaults to "The application panicked (crashed)".

pub fn verbosity(self, v: Verbosity) -> Self

Controls the verbosity level.

Defaults to Verbosity::get_env().

pub fn backtrace_first(self, value: bool) -> Self

Controls the backtrace position.

Defaults to true which causes the backtrace to be printed above the panic.

pub fn most_recent_first(self, value: bool) -> Self

Controls the most-recent-first behavior.

Defaults to true which causes the backtrace to be printed above the panic.

pub fn lineno_suffix(self, value: bool) -> Self

Append the line number as suffix to the filename.

Defaults to false which causes line numbers to be rendered separately. Specifically this renders File "foo.rs:42" instead of File "foo.rs", line 42 which lets some terminals open the editor at the right location on click.

pub fn create_panic_handler(
    self
) -> Box<dyn Fn(&PanicInfo<'_>) + Sync + Send + 'static>

Consumes the settings and creates a panic handler.

pub fn install(self)

Installs the panic handler.
