Struct ValidationWindow 

pub struct ValidationWindow { /* private fields */ }

A bounded TOTP validation window.

The window is expressed in time steps, not seconds. RFC 6238 recommends allowing at most one past step for ordinary network delay. Clock-drift resynchronization policy may deliberately use another bounded value.

Implementations

impl ValidationWindow

pub const CURRENT: Self

Validate only the current time step.

pub const RFC_RECOMMENDED: Self

RFC 6238’s recommended maximum ordinary transmission-delay window.

pub const fn new(past: u16, future: u16) -> Self

Creates a window allowing the given number of past and future steps.

pub const fn past(self) -> u16

Returns the number of accepted past steps.

pub const fn future(self) -> u16

Returns the number of accepted future steps.
