Struct StreamOpenContext

Source

pub struct StreamOpenContext<'a> { /* private fields */ }

Expand description

Borrowed call state for ItemStream::open.

Implementations§

Source §

impl<'a> StreamOpenContext<'a>

Source

pub const fn new( inherited: Option<&'a ComponentStateEnvelope>, stop: &'a StopToken, ) -> Self

Constructs a stream-open call scope.

inherited is the last committed envelope for this stream’s namespace, already checksum-verified, decoded-schema/codec-matched, and migrated by the runtime. None means initial execution, not corruption: a corrupt or unsupported committed envelope fails before any stream is ever opened with it.

Source

pub const fn inherited_state(self) -> Option<&'a ComponentStateEnvelope>

Borrows the last committed state for this stream’s namespace, if any.

Source

pub const fn stop_token(self) -> &'a StopToken

Borrows the cooperative stop token.
