pub struct ContentLength(pub u64);
Expand description
Content-Length
header, defined in
RFC7230
When a message does not have a Transfer-Encoding
header field, a
Content-Length header field can provide the anticipated size, as a
decimal number of octets, for a potential payload body. For messages
that do include a payload body, the Content-Length field-value
provides the framing information necessary for determining where the
body (and message) ends. For messages that do not include a payload
body, the Content-Length indicates the size of the selected
representation.
Note that setting this header will remove any previously set
Transfer-Encoding
header, in accordance with
RFC7230:
A sender MUST NOT send a Content-Length header field in any message that contains a Transfer-Encoding header field.
ABNF
Content-Length = 1*DIGIT
Example values
