pub const ACCEPT_RANGES: HeaderName;Expand description
Marker used by the server to advertise partial request support.
The Accept-Ranges response HTTP header is a marker used by the server to advertise its support of partial requests. The value of this field indicates the unit that can be used to define a range.
