Trait DateTime 

pub trait DateTime {
    const DATE_VALUE_LENGTH: usize;

    // Required methods
    fn with_date<F, O>(&self, f: F) -> O
       where F: FnOnce(&[u8]) -> O;
    fn now(&self) -> Instant;
}

Trait for getting current date/time.

This is usually used by a low resolution of timer to reduce frequent syscall to OS.

Required Associated Constants

const DATE_VALUE_LENGTH: usize

The size hint of slice by Self::date method.

Required Methods

fn with_date<F, O>(&self, f: F) -> O

where F: FnOnce(&[u8]) -> O,

closure would receive byte slice representation of HttpDate.

fn now(&self) -> Instant

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
