Constant actix_http::http::header::TRANSFER_ENCODING

pub const TRANSFER_ENCODING: HeaderName;

Specifies the form of encoding used to safely transfer the entity to the client.

transfer-encoding is a hop-by-hop header, that is applying to a message between two nodes, not to a resource itself. Each segment of a multi-node connection can use different transfer-encoding values. If you want to compress data over the whole connection, use the end-to-end header content-encoding header instead.

When present on a response to a HEAD request that has no body, it indicates the value that would have applied to the corresponding GET message.
