Struct GeneralizedTime

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

Available on crate feature pkcs8 only.

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.

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.
