nested
nested(ctx: Context, errors: ErrorList): [NestedError]
Creates a nested error using ctx to describe where the errors in the list errors happened. This is used to detail information about an actual error location after backtracking has moved the current context away from that location.
The errors parameter will become the error list for the new nested error. However, if errors itself contains only a single nested error, it will be collapsed into the new nested error. There is no need to have a nested error that contains nothing except another nested error.
Parameters
ctx: The context where the nested error(s) happened.errors: The error(s) that happened in that location.
Returns
- Returns a list containing a single nested error, whose own error list will contain the errors that happened at its context's location.
