Broken regex validation - Readme / Docs need update?

[sebadob]

I was using validator v0.16 without any issues.
I did not update to anything newer until now, because my compiler started yelling at me like crazy and I just did not have the time to deal with this.

I now decided to take a deeper look into what the issues are, and its mostly the regex validation that broke.

Just a short example, what I was doing with v0.16:

// the regex was defined somewhere else to be re-used in a lot of places, but that doesn't matter here
pub static RE_TEXT_1000: Lazy<Regex> =
    Lazy::new(|| Regex::new(r"^[a-zA-Z0-9À-ÿ&.,_/()\s-]{0,1000}$").unwrap());

#[derive(Debug, Clone, Serialize, Deserialize, Validate)]
pub struct MyValidatedStruct {
    #[validate(regex(path = "RE_TEXT_1000", code = "^[a-zA-Z0-9À-ÿ&.,_/()\\s-]{0,1000}$"))]
    pub text: String,
}

This breaks when I am trying to use any version past v0.16.
The compiler complains about validator::validation::regex::AsRegex not being implemented:

error[E0277]: the trait bound `once_cell::sync::Lazy<regex::Regex>: validator::validation::regex::AsRegex` is not satisfied

help: consider dereferencing here

The compiler hint with dereferencing is almost correct.
I can fix it with adding * inside the quotes like so:

#[validate(regex(path = "*RE_TEXT_1000"))]

Is this to be expected? If so, an update of readme and docs would probably be nice.

Thanks I've updated the README.
