SubscribeRequestOwnedView

Struct SubscribeRequestOwnedView 

Source
pub struct SubscribeRequestOwnedView(/* private fields */);
Expand description

Self-contained, 'static owned view of a SubscribeRequest message.

Wraps ::buffa::OwnedView<SubscribeRequestView<'static>>: the decoded view and the ::buffa::bytes::Bytes buffer it borrows from travel together, so the handle is 'static and Send + Sync — suitable for async handlers, spawned tasks, and anywhere a 'static bound is required.

Field accessors return borrows tied to &self. Use Self::view to get the full SubscribeRequestView when you need struct patterns, iteration helpers, or to pass the view to lifetime-parameterised code.

Implementations§

Source§

impl SubscribeRequestOwnedView

Source

pub fn decode(bytes: Bytes) -> Result<Self, DecodeError>

Decode an owned view from a ::buffa::bytes::Bytes buffer.

The view borrows directly from the buffer’s data; the buffer is retained inside the returned handle.

§Errors

Returns ::buffa::DecodeError if the buffer contains invalid protobuf data.

Source

pub fn decode_with_options( bytes: Bytes, opts: &DecodeOptions, ) -> Result<Self, DecodeError>

Decode with custom ::buffa::DecodeOptions (recursion limit, max message size).

§Errors

Returns ::buffa::DecodeError if the buffer is invalid or exceeds the configured limits.

Source

pub fn from_owned(msg: &SubscribeRequest) -> Result<Self, DecodeError>

Build from an owned message via an encode → decode round-trip.

§Errors

Returns ::buffa::DecodeError::MessageTooLarge if the message’s encoded size exceeds the 2 GiB protobuf limit, or another ::buffa::DecodeError if the re-encoded bytes are somehow invalid (should not happen for well-formed messages).

Source

pub fn view(&self) -> &SubscribeRequestView<'_>

Borrow the full SubscribeRequestView with its lifetime tied to &self.

Source

pub fn to_owned_message(&self) -> SubscribeRequest

Convert to the owned message type.

Infallible: this type’s constructors wire-decode their buffer, and a view produced by wire decoding always converts. Delegates to ::buffa::OwnedView::to_owned_message, whose contract also governs handles converted from a raw ::buffa::OwnedView.

Source

pub fn bytes(&self) -> &Bytes

The underlying bytes buffer.

Source

pub fn into_bytes(self) -> Bytes

Consume the handle, returning the underlying bytes buffer.

Source

pub fn table(&self) -> &str

Table name registered in the server-side KvSchema.

Field 1: table

Source

pub fn where_sql(&self) -> &str

Scalar SQL boolean expression over this table’s columns (no WHERE keyword). Compiled once before subscribing, then evaluated for each batch. Empty means “emit every decoded row”. Subqueries, aggregates, window functions, and row-expanding expressions are not supported. Stable time functions use the subscription start time. Volatile functions run for each batch. Bounded to keep server-side compile cost predictable.

Field 2: where_sql

Source

pub fn since_sequence_number(&self) -> Option<u64>

Resume cursor over the underlying store batch log. Use SubscribeResponse.sequence_number + 1 to resume after a disconnect.

Field 3: since_sequence_number
