Struct PasswordContext 

pub struct PasswordContext<'a> {
    pub username: Option<&'a str>,
    pub email: Option<&'a str>,
}

The user context a validator can compare a candidate password against.

Both fields are Option because not every call site has a user: a bare strength check (e.g. a password-meter endpoint) passes PasswordContext::empty(), while create_user / set_password fill in what they know. The similarity validator simply skips any field that’s None.

Fields

username: Option<&'a str>

The account’s login handle, when known.

email: Option<&'a str>

The account’s email address, when known. The similarity check uses the local-part (before the @) as well as the whole string.

Implementations

impl<'a> PasswordContext<'a>

pub fn empty() -> Self

A context with no user attributes — the similarity validator is a no-op against it. Use for standalone strength checks.

pub fn for_username(username: &'a str) -> Self

A context carrying just a username.

pub fn new(username: Option<&'a str>, email: Option<&'a str>) -> Self

A context carrying a username and an email.
