[−][src]Struct headers::Vary
Vary
header, defined in RFC7231
The "Vary" header field in a response describes what parts of a request message, aside from the method, Host header field, and request target, might influence the origin server's process for selecting and representing this response. The value consists of either a single asterisk ("*") or a list of header field names (case-insensitive).
ABNF
Vary = "*" / 1#field-name
Example values
accept-encoding, accept-language
Example
use headers::Vary; let vary = Vary::any();
Implementations
impl Vary
[src]
pub fn any() -> Vary
[src]

header.
pub fn is_any(&self) -> bool
[src]
Check if this includes *
.
pub fn iter_strs(&self) -> impl Iterator<Item = &str>
[src]
Iterate the header names of this Vary
.
