pub enum Error {
    IndexSize = 1,

}

Corresponds to the DOM DomException type.

Specification

DOM operations only raise exceptions in “exceptional” circumstances, i.e., when an operation is impossible to perform (either for logical reasons, because data is lost, or because the implementation has become unstable). In general, DOM methods return specific error values in ordinary processing situation, such as out-of-bound errors when using NodeList.

Variants

IndexSize = 1

If index or size is negative, or greater than the allowed value

StringSize = 2

If the specified range of text does not fit into a DOMString

HierarchyRequest = 3

If any node is inserted somewhere it doesn’t belong

WrongDocument = 4

If a node is used in a different document than the one that created it (that doesn’t support it)

InvalidCharacter = 5

If an invalid or illegal character is specified, such as in a name. See production 2 in the XML specification for the definition of a legal character, and production 5 for the definition of a legal name character.

NoDataAllowed = 6

If data is specified for a node which does not support data

NoModificationAllowed = 7

If an attempt is made to modify an object where modifications are not allowed

NotFound = 8

If an attempt is made to reference a node in a context where it does not exist

NotSupported = 9

If the implementation does not support the requested type of object or operation

InUseAttribute = 10

If an attempt is made to add an attribute that is already in use elsewhere

InvalidState = 11

If an attempt is made to use an object that is not, or is no longer, usable (introduced in DOM Level 2)

Syntax = 12

If an invalid or illegal string is specified (introduced in DOM Level 2)

InvalidModification = 13

If an attempt is made to modify the type of the underlying object (introduced in DOM Level 2)

Namespace = 14

If an attempt is made to create or change an object in a way which is incorrect with regard to namespaces (introduced in DOM Level 2)

InvalidAccess = 15

If a parameter or an operation is not supported by the underlying object (introduced in DOM Level 2)

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, f: &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(value: DOMError) -> Self

Converts to this type from the input type.

impl<T> From<Error> for Result<T>

fn from(val: Error) -> Self

Converts to this type from the input type.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
