Implementations

impl LxAppError

pub fn requires_runtime_upgrade(detail: impl Into<String>) -> LxAppError

This host’s runtime is below the package’s minRuntime.

pub fn is_requires_runtime_upgrade(&self) -> bool

pub fn detail(&self) -> Option<&str>

The message without the variant’s prefix.

Every variant’s Display prepends or appends its own label, which reads as noise once the caller has already framed the failure: nesting them produces “Invalid parameter: iconPath: Invalid parameter: …”, and the variants that append produce “directory traversal not allowed not found”. Use this when embedding one error’s reason inside another’s sentence.

Trait Implementations

impl Clone for LxAppError

fn clone(&self) -> LxAppError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LxAppError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for LxAppError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for LxAppError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
