Package version eg. v8, v9:

v9

Issue, Question or Enhancement:

Is it possible to use oneof validation with values containing space character? Tried with single quote but it did not seem to work.

Code sample, to showcase or reproduce:

type Data struct {
    Status string `json:"status" validate:"required,oneof='Awaiting Verification' 'Verified' 'Failed Veri

For completion, we should offer an As method like the one in Go 1.13 errors (https://golang.org/pkg/errors/#As). We should try to make this more reliable than Go's version by preventing panics: "As will panic if target is not a non-nil pointer to either a type that implements error, or to any interface type." Seems like we could just return false in these cases instead.

This case should just be passed directly to the parent handler

This will involve adding a feature flag for Rust 1.46, then adding #[track_caller] to the context selector methods like build and fail.
