Enum HeapError 

pub enum HeapError {
    OutOfMemory,
    DuplicateKey,
    PrototypeCycle,
}

Variants

OutOfMemory

The heap cap would be crossed even after a collection. The caller turns it into the JavaScript InternalError.

DuplicateKey

add_property on a key the object already has.

PrototypeCycle

set_prototype would create a cycle.

impl Eq for HeapError

impl Error for HeapError

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 PartialEq for HeapError

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

Equality operator ==.

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

Inequality operator !=.
