Struct GeneralizedTime

pub struct GeneralizedTime(/* private fields */);

ASN.1 GeneralizedTime type.

This type implements the validity requirements specified in RFC 5280 Section 4.1.2.5.2, namely:

For the purposes of this profile, GeneralizedTime values MUST be expressed in Greenwich Mean Time (Zulu) and MUST include seconds (i.e., times are YYYYMMDDHHMMSSZ), even where the number of seconds is zero. GeneralizedTime values MUST NOT include fractional seconds.

Implementations

impl GeneralizedTime

pub fn from_date_time(datetime: DateTime) -> Self

impl Ord for GeneralizedTime

fn cmp(&self, other: &GeneralizedTime) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for GeneralizedTime

fn eq(&self, other: &GeneralizedTime) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
