Module wire 

Shared Wire values and the mod-side transport.

Structs

Fields

A hook record’s writable fields, in declaration order. Sharing these tuple codecs avoids generating and compiling a separate native codec for every named point record.

Id

A resource’s id: generation in the high half, slot in the low.

ReadOnly

A field which crosses with a record but is not a declared writeback destination.

Reader

A buffer values are read from.

Refused

A call record refused before it can be encoded, such as an oversized owned snapshot. It follows the normal Writer error path instead of sending a truncated call.

ResourceScope

Activates a call’s codec, including guest-to-host-to-guest callbacks. Dropping scopes out of order unlinks them: a retained inner guard cannot revive an expired outer codec. Slots are reused, so steady-state calls allocate no scope bookkeeping.

ScopeLease

A detached value lease. It never installs a codec or attests a native call root. Its lifetime is independent of the active resource scopes.

ScopeToken

A non-owning native lease. Checking it never retains the scope, codec, or pointee.

Slots

A generational slot map. Generation zero is reserved for protocol control values; exhausted generations retire their slot rather than wrapping and reviving an old id.

Stale

The id names no live value: it was freed, its call ended, or it was never given out.

Writer

A buffer values are written to. Reuse one to keep the allocation.

Enums

ScopeError

A lease’s scope ended, or the caller left its owning thread.

WireError

Why a buffer is not a value of the type it was read as.

Constants

MAX_DEPTH

The deepest nesting of one value (a component of a component of…) a reader accepts.

Traits

Put

What can be written: every Wire value, and the borrowed forms a call passes (&str, &[T], Option<&T>), which are written as the owned value they stand for.

Record

A mutable hook argument, erased without changing its wire representation. Replies are decoded completely before any field is assigned.

ResourceCodec

Resolves resource identities for the side of a synchronous boundary call.

Wire

A type with a wire form.

Functions

borrow_token

The nearest live runtime root, never an attestation supplied by a user codec.
