Struct actix_web::cookie::time::Duration [−][src]
pub struct Duration { /* fields omitted */ }Expand description
A span of time with nanosecond precision.
Each Duration is composed of a whole number of seconds and a fractional part represented in
nanoseconds.
This implementation allows for negative durations, unlike core::time::Duration.
