Struct boa_engine::error::JsErasedError
source · pub struct JsErasedError { /* private fields */ }
Expand description
Erased version of JsError
.
This is mainly useful to convert a JsError
into an Error
that also
implements Send + Sync
, which makes it compatible with error reporting tools
such as anyhow
, eyre
or miette
.
Generally, the conversion from JsError
to JsErasedError
is unidirectional,
since any JsError
that is a JsValue
is converted to its string representation
instead. This will lose information if that value was an object, a symbol or a big int.
Implementations§
source§impl JsErasedError
impl JsErasedError
sourcepub const fn as_opaque(&self) -> Option<&str>
pub const fn as_opaque(&self) -> Option<&str>
Gets the inner str
if the error is an opaque error,
or None
otherwise.
sourcepub const fn as_native(&self) -> Option<&JsErasedNativeError>
pub const fn as_native(&self) -> Option<&JsErasedNativeError>
Gets the inner JsErasedNativeError
if the error is a native
error, or None
otherwise.
