Implementations

impl Error

pub fn device_not_found(device_id: impl Into<String>) -> Self

Create a device not found error.

pub fn point_not_found( device_id: impl Into<String>, point_id: impl Into<String>, ) -> Self

Create a data point not found error.

pub fn capacity_exceeded( current: usize, max: usize, resource: impl Into<String>, ) -> Self

Create a capacity exceeded error.

pub fn access_denied( point_id: impl Into<String>, operation: impl Into<String>, mode: impl Into<String>, ) -> Self

Create an access denied error.

pub fn out_of_range( point_id: impl Into<String>, value: f64, min: f64, max: f64, ) -> Self

Create an out of range error.

pub fn validation(errors: ValidationErrors) -> Self

Create a validation error from a ValidationErrors instance.

pub fn is_recoverable(&self) -> bool

Check if this error is recoverable.

pub fn is_validation(&self) -> bool

Check if this is a validation error.

pub fn is_not_found(&self) -> bool

Check if this is a not found error.

pub fn severity(&self) -> ErrorSeverity

Get error severity.

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(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.
