Implementations

impl Error

pub fn plugin_not_found(name: impl Into<String>) -> Self

Create a plugin not found error.

pub fn invalid_manifest(msg: impl Into<String>) -> Self

Create an invalid manifest error.

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

Create a missing manifest field error.

pub fn api_version_mismatch( required: impl Into<String>, provided: impl Into<String>, ) -> Self

Create an API version mismatch error.

pub fn missing_capability(cap: impl Into<String>) -> Self

Create a missing capability error.

pub fn dependency_not_satisfied( name: impl Into<String>, version: impl Into<String>, ) -> Self

Create a dependency not satisfied error.

pub fn init_failed(msg: impl Into<String>) -> Self

Create an initialization failed error.

pub fn execution_failed(msg: impl Into<String>) -> Self

Create an execution failed error.

pub fn invalid_state( expected: impl Into<String>, actual: impl Into<String>, ) -> Self

Create an invalid state error.

pub fn is_recoverable(&self) -> bool

Returns true if this error is recoverable.

pub fn should_reload(&self) -> bool

Returns true if this error should trigger a reload.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
