Struct ParseDerivationStyleError 

#[non_exhaustive]
pub struct ParseDerivationStyleError { /* private fields */ }

Error returned when FromStr fails on a chain’s DerivationStyle.

Carries the chain name, the rejected input, and the full accepted token list (aliases included). The Display impl produces a single actionable diagnostic so CLI error output needs no further massaging.

Implementations

impl ParseDerivationStyleError

pub fn new( chain: &'static str, input: impl Into<String>, accepted: &'static [&'static str], ) -> Self

Construct a new error.

chain is typically a short lowercase identifier ("ethereum", "solana", "ton"); accepted must list every alias the chain’s FromStr implementation recognises, in the order they should appear in the human-readable message.

pub const fn chain(&self) -> &'static str

Chain that rejected the input ("ethereum", "solana", …).

pub fn input(&self) -> &str

The user-supplied string that failed to parse.

pub const fn accepted(&self) -> &'static [&'static str]

Full accepted alias list, in display order.

Trait Implementations

impl Clone for ParseDerivationStyleError

fn clone(&self) -> ParseDerivationStyleError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseDerivationStyleError

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

Formats the value using the given formatter.

impl Display for ParseDerivationStyleError

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

Formats the value using the given formatter.

impl Error for ParseDerivationStyleError

Available on crate feature std only.

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 PartialEq for ParseDerivationStyleError

fn eq(&self, other: &ParseDerivationStyleError) -> 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.
