Expand description
A JsError
represents an exception coming from V8, with stack frames and
line numbers. The deno_cli crate defines another JsError
type, which wraps
the one defined here, that adds source map support and colorful formatting.
When updating this struct, also update errors_are_equal_without_cause() in
fmt_error.rs.

Implementations§
source§impl JsError
impl JsError
sourcepub fn is_same_error(&self, other: &JsError) -> bool
pub fn is_same_error(&self, other: &JsError) -> bool
Compares all properties of JsError, except for JsError::cause. This function is used to detect that 2 JsError objects in a JsError::cause chain are identical, ie. there is a recursive cause.
We don’t have access to object identity here, so we do it via field comparison. Ideally this should be able to maintain object identity somehow.
