ConnectException class final

ConnectException captures four pieces of information: a Code, an error message, an optional cause of the error, and an optional collection of arbitrary Protobuf messages called "details".

Because developer tools typically print just the toString message, we prefix it with the status code, so that the most important information is always visible immediately.

Error details are wrapped with google.protobuf.Any on the wire, so that a server or middleware can attach arbitrary data to an error.

final

details → List<ErrorDetail>

Incoming error details are stored in this property.

final

hashCode → int

The hash code for this object.
