Trait DateTime 

pub trait DateTime {
    const DATE_SIZE_HINT: usize = DATE_VALUE_LENGTH;

    // Required methods
    fn with_date<F, O>(&self, f: F) -> O
       where F: FnOnce(&[u8]) -> O;
    fn with_date_header<F, O>(&self, f: F) -> O
       where F: FnOnce(&HeaderValue) -> 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.

Provided Associated Constants

const DATE_SIZE_HINT: usize = DATE_VALUE_LENGTH

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

where F: FnOnce(&HeaderValue) -> O,

fn now(&self) -> Instant

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
