Function Wrapf

errors/gerror/gerror_api.go:70–81

Wrapf returns an error annotating err with a stack trace at the point Wrapf is called, and the format specifier. It returns nil if given `err` is nil. Note that it does not lose the error code of wrapped error, as it inherits the error code from it.

// WrapSkip wraps error with text. It returns nil if given err is nil.
// The parameter `skip` specifies the stack callers skipped amount.
