Struct SyntheticIds 

pub struct SyntheticIds { /* private fields */ }

Fabricated per-stream keys for wires that carry none.

Every id-less wire mints keys the same way — a MintKind plus a counter or the wire’s own unsigned index — and the result is a StreamPartId::Minted that, like every stream key, structurally cannot reach a request or a public stream item.

Implementations

impl SyntheticIds

pub fn new(kind: MintKind) -> Self

A minter for kind.

pub fn output() -> Self

Keys for the Responses output_index fallback.

pub fn tool() -> Self

Keys for tool-call fragments whose wire supplies no tool-call id.

pub fn text() -> Self

Keys for text blocks opened by a bare Message.

pub fn mint(&mut self) -> StreamPartId

Mint the next counter-based key (vercel’s blockCounter++ pattern).

Trait Implementations

impl Debug for SyntheticIds

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

Formats the value using the given formatter.
