Struct Lifetime

pub struct Lifetime { /* private fields */ }

The lifetime represents the times between which clients will consider a KeyPackage valid. This time is represented as an absolute time, measured in seconds since the Unix epoch (1970-01-01T00:00:00Z). A client MUST NOT use the data in a KeyPackage for any processing before the not_before date, or after the not_after date.

Applications MUST define a maximum total lifetime that is acceptable for a KeyPackage, and reject any KeyPackage where the total lifetime is longer than this duration.This extension MUST always be present in a KeyPackage.

// draft-ietf-mls-protocol-16
struct {
    uint64 not_before;
    uint64 not_after;
} Lifetime;

Implementations

impl Lifetime

pub fn new(t: u64) -> Self

Create a new lifetime with lifetime t (in seconds). Note that the lifetime is extended 1h into the past to adapt to skewed clocks, i.e. not_before is set to now - 1h.

pub fn is_valid(&self) -> bool

Returns true if this lifetime is valid.

pub fn has_acceptable_range(&self) -> bool

ValSem(openmls/annotations#32): Applications MUST define a maximum total lifetime that is acceptable for a LeafNode, and reject any LeafNode where the total lifetime is longer than this duration.

pub fn not_before(&self) -> u64

Returns the “not before” timestamp of the KeyPackage.

pub fn not_after(&self) -> u64

Returns the “not after” timestamp of the KeyPackage.

Trait Implementations

impl Clone for Lifetime

fn clone(&self) -> Lifetime

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Lifetime

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

Formats the value using the given formatter.

impl Default for Lifetime

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Lifetime

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Deserialize for Lifetime

fn tls_deserialize<R: Read>(bytes: &mut R) -> Result<Self, Error>

This function deserializes the bytes from the provided a std::io::Read and returns the populated struct.

fn tls_deserialize_exact(bytes: impl AsRef<[u8]>) -> Result<Self, Error>

where Self: Sized,

This function deserializes the provided bytes and returns the populated struct. All bytes must be consumed.

impl DeserializeBytes for Lifetime

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

This function deserializes the bytes from the provided a &[u8] and returns the populated struct, as well as the remaining slice.

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

where Self: Sized,

This function deserializes the provided bytes and returns the populated struct. All bytes must be consumed.

impl PartialEq for Lifetime

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

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

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

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

impl Serialize for &Lifetime

fn tls_serialize<W: Write>(&self, writer: &mut W) -> Result<usize, Error>

Serialize self and write it to the writer. The function returns the number of bytes written to writer.

fn tls_serialize_detached(&self) -> Result<Vec<u8>, Error>

Serialize self and return it as a byte vector.

impl Serialize for Lifetime

fn tls_serialize<W: Write>(&self, writer: &mut W) -> Result<usize, Error>

Serialize self and write it to the writer. The function returns the number of bytes written to writer.

fn tls_serialize_detached(&self) -> Result<Vec<u8>, Error>

Serialize self and return it as a byte vector.

impl Serialize for Lifetime

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Size for &Lifetime

fn tls_serialized_len(&self) -> usize

impl Size for Lifetime

fn tls_serialized_len(&self) -> usize
