Struct Parts

#[non_exhaustive]
pub struct Parts<T> {
    pub io: T,
    pub read_buf: Bytes,
}

The deconstructed parts of an Upgraded type.

Includes the original IO type, and a read buffer of bytes that the HTTP state machine may have already read before completing an upgrade.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

io: T

The original IO object used before the upgrade.

read_buf: Bytes

A buffer of bytes that have been read but not processed as HTTP.

For instance, if the Connection is used for an HTTP upgrade request, it is possible the server sent back the first bytes of the new protocol along with the response upgrade.

You will want to check for any existing bytes if you plan to continue communicating on the IO object.

Trait Implementations

impl<T: Debug> Debug for Parts<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
