Struct mozjs_sys::jsapi::mozilla::ErrorPropagationTag

#[repr(C)]
pub struct ErrorPropagationTag {
    pub _address: u8,
}

A tag used to differentiate between GenericErrorResult created by the Err function (completely new error) and GenericErrorResult created by the Result::propagateErr function (propagated error). This can be used to track error propagation and eventually produce error stacks for logging/debugging purposes.

Fields

_address: u8

Trait Implementations

impl Clone for ErrorPropagationTag

fn clone(&self) -> ErrorPropagationTag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorPropagationTag

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

Formats the value using the given formatter.

impl PartialEq for ErrorPropagationTag

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

This method tests for self and other values to be equal, and is used by ==.

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

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