What an executed action actually did.

Unlike ProxyEvent this derives PartialEq and Eq: destructure the event, then assert_eq! on what comes out. See ProxyEvent’s own rustdoc for the shape.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ForwardedVerbatim

The original bytes were forwarded.

Replaced

Replacement bytes were forwarded.

Fields

bytes: usize

How many bytes were written.

Elided

An object was removed. renumbered_successor is true when the next object on the stream has to be re-encoded against the one now in front of it: its leading ID varint rewritten on a subgroup stream of drafts 14-19, its whole framing re-encoded on a fetch stream of drafts 15-19.

It says a fix-up is owed, not that the bytes moved. A survivor that already stated everything it needed comes through unchanged, and the debt is settled all the same.

Fields

renumbered_successor: bool

Whether a successor fix-up is now pending.

Queued

The unit was queued for later release.

Fields

release_at: Instant

When it is due.

Truncated

A prefix was written and the stream reset.

forwarded counts bytes handed to the transport, not bytes the peer observed. quinn clears the peer’s receive assembler when the reset is processed, so the peer may observe fewer — never more.

Fields

forwarded: usize

Bytes of this unit written before the reset.

code: u64

The reset code, as the action stated it.

code_defined: bool

false when the draft defines no stream-reset code vocabulary (drafts 07-10), so code is a choice rather than a claim.

StreamReset

The destination stream was reset.

Fields

code: u64

The reset code.

code_defined: bool

false when the draft defines no stream-reset code vocabulary (drafts 07-10), so code is a choice rather than a claim.

StreamRejected

The stream was never forwarded.

Fields

code: u64

The code the source was stopped with.

SessionClosing

A session close was requested.

Fields

code: u32

The session termination code.

Dropped

The unit was not forwarded.
