Struct rkyv::with::UnixTimestamp

pub struct UnixTimestamp;

A wrapper that converts a SystemTime to a Duration since UNIX_EPOCH.

If the serialized time occurs before the UNIX epoch, serialization will panic during resolve. The resulting archived time will be an ArchivedDuration relative to the UNIX epoch.

Regular serializers don’t support the custom error handling needed for this type by default. To use this wrapper, a custom serializer with an error type satisfying <S as Fallible>::Error: From<UnixTimestampError> must be provided.

Example

use rkyv::{Archive, with::UnixTimestamp};
use std::time::SystemTime;

#[derive(Archive)]
struct Example {
    #[with(UnixTimestamp)]
    time: SystemTime,
}

Trait Implementations

impl ArchiveWith<SystemTime> for UnixTimestamp

type Archived = ArchivedDuration

The archived type of a With<F, Self>.

type Resolver = ()

The resolver of a With<F, Self>.

unsafe fn resolve_with( field: &SystemTime, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

Resolves the archived type using a reference to the field type F.
