Struct hyper::header::UserAgent [-] [+] [src]

pub struct UserAgent(pub String);

User-Agent header, defined in RFC7231

The User-Agent header field contains information about the user agent originating the request, which is often used by servers to help identify the scope of reported interoperability problems, to work around or tailor responses to avoid particular user agent limitations, and for analytics regarding browser or operating system use. A user agent SHOULD send a User-Agent field in each request unless specifically configured not to do so.

ABNF

User-Agent = product *( RWS ( product / comment ) )
product         = token ["/" product-version]
product-version = token

Example values

Notes

The parser does not split the value
