pub enum ConditionalHeader<Etag, DateTime> {
    IfNoneMatch,
    IfMatch(Etag),
    IfUnmodifiedSince(DateTime),
}

HTTP Conditional Header

Conditional headers used in the idempotency verification.

Variants

IfNoneMatch

If-None-Match

Allow the request only if the resource does not exists.

Used to avoid ID colisions creating resources.

IfMatch(Etag)

If-Match

This header will allow the request to proceed only if the resource match with the specified Etag.

Used in resource updates to avoid the lost update problem.

IfUnmodifiedSince(DateTime)

If-Unmodified-Since

Accept the request if the resource has not been modified after the date specified.

Trait Implementations

impl<Etag: Debug, DateTime: Debug> Debug for ConditionalHeader<Etag, DateTime>

impl<Etag: PartialEq, DateTime: PartialEq> PartialEq for ConditionalHeader<Etag, DateTime>

fn eq(&self, other: &ConditionalHeader<Etag, DateTime>) -> 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.
