Struct DefaultPasswordPolicy 

pub struct DefaultPasswordPolicy {
    pub min_len: usize,
}

Length-only password policy. Default min_len is 10 — the secure-by-default baseline R1 ships with: long enough to defeat trivial guessing under Argon2id + per-IP rate-limiting (NIST SP 800-63B’s recommended length floor is 8, with longer being preferable), short enough not to drive operators toward sticky- note workarounds. Production / regulated deployments are encouraged to override to 12+ via crate::admin::Admin::password_policy; high-sensitivity deployments may want 16+ paired with an organisational complexity rule or breach blocklist.

The framework deliberately ships no complexity-class rules (“must contain a symbol”, “must include uppercase”) in the default — they demonstrably push humans toward predictable patterns without improving entropy meaningfully (NIST SP 800-63B Appendix A). Projects that need them implement a custom PasswordPolicy.

Implementations

impl DefaultPasswordPolicy

pub const fn new() -> Self

New policy with the framework’s default floor (min_len = 10).

pub const fn with_min_len(min_len: usize) -> Self

New policy with an explicit floor. Useful for projects that want a stronger length baseline without authoring a full PasswordPolicy impl.

Trait Implementations

impl Clone for DefaultPasswordPolicy

fn clone(&self) -> DefaultPasswordPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DefaultPasswordPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DefaultPasswordPolicy

fn default() -> Self

Returns the “default value” for a type.

impl PasswordPolicy for DefaultPasswordPolicy

fn validate(&self, candidate: &str) -> Result<(), PasswordPolicyError>

Approve or reject the candidate.

fn min_length(&self) -> usize

The minimum length the policy enforces, in Unicode chars. Templates display this on the new-password form so users see the floor before submitting.
