Struct PromiseError 

pub struct PromiseError { /* private fields */ }

Why a promise of the page was rejected: the name and the message of the error it was rejected with (for a reason that is not an error, an empty name and the reason as text).

Implementations

impl PromiseError

pub fn new(name: impl Into<String>, message: impl Into<String>) -> Self

Creates the error of a rejection.

pub fn name(&self) -> &str

The name of the error, such as NotAllowedError.

pub fn message(&self) -> &str

The message of the error.

Trait Implementations

impl Clone for PromiseError

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 PromiseError

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

Formats the value using the given formatter.

impl Display for PromiseError

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

Formats the value using the given formatter.

impl Eq for PromiseError

impl Error for PromiseError

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<PromiseError> for Error

fn from(error: PromiseError) -> Self

The error as an I/O error whose payload is the rejection (read it back with get_ref and downcast_ref::<PromiseError> for its name and message). The kind follows the name of the DOM exception, so that a caller can tell a missing item, a refused permission and a cancelled request apart; any other name is std::io::ErrorKind::Other.

impl PartialEq for PromiseError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
