Implementations

impl<E: Error> EthAppError<E>

pub fn is_user_rejected(&self) -> bool

Check if error is due to user rejection

pub fn is_transport_error(&self) -> bool

Check if error is due to transport/communication issues

pub fn is_invalid_input(&self) -> bool

Check if error is due to invalid input parameters

Trait Implementations

impl<E: Clone + Error> Clone for EthAppError<E>

fn clone(&self) -> EthAppError<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug + Error> Debug for EthAppError<E>

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

Formats the value using the given formatter.

impl<E: Error> Display for EthAppError<E>

where LedgerAppError<E>: Display,

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

Formats the value using the given formatter.

impl<E: Error> Error for EthAppError<E>

where LedgerAppError<E>: Error + 'static, Self: Debug + Display,

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl<E: Error> From<LedgerAppError<E>> for EthAppError<E>

fn from(source: LedgerAppError<E>) -> Self

Converts to this type from the input type.

impl<E: PartialEq + Error> PartialEq for EthAppError<E>

fn eq(&self, other: &EthAppError<E>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
