Enum SignerError 

#[non_exhaustive]
pub enum SignerError {
    AuthorMismatch(UnsignedEventError),
    Rejected {
        message: String,
        code: Option<String>,
    },
    Backend(Box<dyn StdError + Send + Sync>),
    Unsupported(&'static str),
}

Errors raised by a NostrSigner.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AuthorMismatch(UnsignedEventError)

The signer’s public key did not match the unsigned event author.

Rejected

The remote signer rejected the request (e.g. user denied a NIP-46 prompt, NIP-07 returned null, …).

code carries the machine-readable NIP-46 error string when the backend supplies one ("user_rejected", "timeout", etc.); leave it None for backends without a structured error channel.

Fields

message: String

Human-readable explanation, suitable for display.

code: Option<String>

Machine-readable error code when supplied by the backend.

Backend(Box<dyn StdError + Send + Sync>)

The signer could not communicate with its backend.

Unsupported(&'static str)

The signer does not implement the requested operation.

Implementations

impl SignerError

pub fn backend<E>(err: E) -> Self

where E: StdError + Send + Sync + 'static,

Wrap an arbitrary error as a backend failure.

pub fn rejected<S>(message: S) -> Self

where S: Into<String>,

Convenience constructor for SignerError::Rejected without a structured backend code (NIP-07, sandbox signers, etc.).

pub fn rejected_with_code<S, C>(message: S, code: C) -> Self

where S: Into<String>, C: Into<String>,

Convenience constructor for SignerError::Rejected with a machine-readable code (typically the NIP-46 error string).

Trait Implementations

impl Debug for SignerError

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

Formats the value using the given formatter.

impl Display for SignerError

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

Formats the value using the given formatter.

impl Error for SignerError

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 From<UnsignedEventError> for SignerError

fn from(source: UnsignedEventError) -> Self

Converts to this type from the input type.
