Enum x509_cert::time::Time

pub enum Time {
    UtcTime(UtcTime),
    GeneralTime(GeneralizedTime),
}

X.501 Time as defined in RFC 5280 Section 4.1.2.5.

Schema definition from RFC 5280 Appendix A:

Time ::= CHOICE {
     utcTime        UTCTime,
     generalTime    GeneralizedTime
}

Variants

UtcTime(UtcTime)

Legacy UTC time (has 2-digit year, valid from 1970 to 2049).

Note: RFC 5280 specifies 1950-2049, however due to common operations working on UNIX_EPOCH this implementation’s lower bound is 1970.

GeneralTime(GeneralizedTime)

Modern GeneralizedTime encoding with 4-digit year.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for Time

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl<'__der_lifetime> Choice<'__der_lifetime> for Time

fn can_decode(tag: Tag) -> bool

Is the provided Tag decodable as a variant of this CHOICE?

impl Clone for Time

fn clone(&self) -> Time

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Time

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

Formats the value using the given formatter.

impl<'__der_lifetime> Decode<'__der_lifetime> for Time

fn decode<R: Reader<'__der_lifetime>>(reader: &mut R) -> Result<Self>

Attempt to decode this message using the provided decoder.

fn from_der(bytes: &'a [u8]) -> Result<Self, Error>

Parse Self from the provided DER-encoded byte slice.

impl Display for Time

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

Formats the value using the given formatter.

impl EncodeValue for Time

fn encode_value(&self, encoder: &mut impl Writer) -> Result<()>

Encode value (sans [Tag]+Length header) as ASN.1 DER using the provided Writer.

fn value_len(&self) -> Result<Length>

Compute the length of this value (sans [Tag]+Length header) when encoded as ASN.1 DER.

fn header(&self) -> Result<Header, Error>

where Self: Tagged,

Get the Header used to encode this value.

impl From<&Time> for SystemTime

Available on crate feature std only.

fn from(time: &Time) -> SystemTime

Converts to this type from the input type.

impl From<GeneralizedTime> for Time

fn from(time: GeneralizedTime) -> Time

Converts to this type from the input type.

impl From<Time> for SystemTime

Available on crate feature std only.

fn from(time: Time) -> SystemTime

Converts to this type from the input type.

impl From<UtcTime> for Time

fn from(time: UtcTime) -> Time

impl PartialEq for Time

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Available on crate feature std only.

type Error = Error

Return an Ordering between value portion of TLV-encoded self and other when serialized as ASN.1 DER.

impl Copy for Time

impl Eq for Time

impl StructuralEq for Time

impl StructuralPartialEq for Time
