Struct RequestError 

pub struct RequestError { /* private fields */ }

Indicates that a render request could not be validated.

Error::source is always None: validation has no underlying cause beyond the stable code and message.

Implementations

impl RequestError

pub const fn code(&self) -> ErrorCode

Returns the stable machine-readable request error code.

pub const fn field(&self) -> &str

Returns the rejected canonical request field.

pub fn asset_id(&self) -> Option<&str>

Returns the applicable supplemental asset ID.

pub const fn option(&self) -> Option<&str>

Returns the applicable format-option name.

pub fn details(&self) -> Option<&DiagnosticDetails>

Returns typed details of this failure: always DiagnosticDetails::RequestValue, naming the rejected field and, where they apply, the supplemental asset and format option.

pub fn descriptor(&self) -> ErrorDescriptor

Returns this failure’s stable serializable descriptor.

Trait Implementations

impl Clone for RequestError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequestError

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

Formats the value using the given formatter.

impl Display for RequestError

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

Formats the value using the given formatter.

impl Error for RequestError

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.
