Enum Error

pub enum Error {
    GlobalScopeNotFound,
    CryptoUnreachable,
    DomException(String, String),
    Unknown,
}

General errors that can occur when interacting with the Web Crypto API.

Variants

GlobalScopeNotFound

Indicates that the global scope (window or worker context) could not be accessed. This might occur in environments where the Web API is not available.

CryptoUnreachable

Indicates that the Web Crypto API is not available in the current environment. This might occur in environments that don’t support the Web Crypto API or where it’s been disabled.

DomException(String, String)

Represents a DOM exception with a name and message. Provides more detailed information about Web API-specific errors.

Fields

• 0 - The name of the DOM exception
• 1 - The error message

Unknown

Represents an unknown or unexpected error that couldn’t be classified. When the log-error feature is enabled, these errors will be logged to the console.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

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 DecryptionError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for EncryptionError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ImportKeyError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for NonceError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<JsValue> for Error

fn from(value: JsValue) -> Self

Converts a JavaScript value into a Rust Error.

If the JavaScript value is a DOMException, it will be converted into a Error::DomException with the appropriate name and message. Otherwise, it will be converted into Error::Unknown.

When the log-error feature is enabled, unknown errors will be logged to the console for debugging purposes.
