Struct Accept 

pub struct Accept(pub NonEmptySmallVec<7, QualityValue<Mime>>);

Available on crate features http and std only.

Accept header, defined in RFC7231

The Accept header field can be used by user agents to specify response media types that are acceptable. Accept header fields can be used to indicate that the request is specifically limited to a small set of desired types, as in the case of a request for an in-line image

ABNF

Accept = #( media-range [ accept-params ] )

media-range    = ( "*/*"
                 / ( type "/" "*" )
                 / ( type "/" subtype )
                 ) *( OWS ";" OWS parameter )
accept-params  = weight *( accept-ext )
accept-ext = OWS ";" OWS token [ "=" ( token / quoted-string ) ]

Example values

• audio/*; q=0.2, audio/basic
• text/plain; q=0.5, text/html, text/x-dvi; q=0.8, text/x-c
