Create a registry error from any error type.

pub fn api_response_error(package: impl Into<String>, error: Error) -> Self

Create an API response error.

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

Create an invalid structure error.

pub fn missing_field( section: impl Into<String>, field: impl Into<String>, ) -> Self

Trait Implementations

impl Debug for NpmError

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

Formats the value using the given formatter.

impl Display for NpmError

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

Formats the value using the given formatter.

impl Error for NpmError

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.
