Struct ListTransactionsResponse 

#[non_exhaustive]
pub struct ListTransactionsResponse {
    pub transaction: Option<ExecutedTransaction>,
    pub watermark: Option<Watermark>,
    pub end: Option<QueryEnd>,
}

Response message for LedgerService.ListTransactions.

Every frame carries a watermark with a safe resume cursor. A frame with transaction set delivers one matching item; a frame without it reports scan progress or terminal completion. Watermarks never regress in the requested ordering but may repeat.

end is set exactly once, on the final frame of a successful stream. For QUERY_END_REASON_ITEM_LIMIT, that frame also carries the final item. For every other end reason, the final frame has no transaction payload.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

transaction: Option<ExecutedTransaction>

One matching transaction. Its position within the containing checkpoint is reported by ExecutedTransaction.transaction_index.

watermark: Option<Watermark>

Progress watermark as of this frame. Present on every frame. A ScanLimit terminal watermark may repeat the previous frame’s cursor when its authoritative scan frontier was already emitted.

end: Option<QueryEnd>

Set exactly once, on the final frame of a successful query stream.

impl ListTransactionsResponse

pub const fn const_default() -> Self

pub fn transaction(&self) -> &ExecutedTransaction

Returns the value of transaction, or the default value if transaction is unset.

pub fn transaction_opt_mut(&mut self) -> Option<&mut ExecutedTransaction>

If transaction is set, returns Some with a mutable reference to the value; otherwise returns None.

Sets transaction with the provided value.

pub fn watermark(&self) -> &Watermark

Returns the value of watermark, or the default value if watermark is unset.

pub fn watermark_opt_mut(&mut self) -> Option<&mut Watermark>

If watermark is set, returns Some with a mutable reference to the value; otherwise returns None.

pub fn watermark_mut(&mut self) -> &mut Watermark

Returns a mutable reference to watermark. If the field is unset, it is first initialized with the default value.

pub fn end(&self) -> &QueryEnd

Returns the value of end, or the default value if end is unset.

pub fn end_opt_mut(&mut self) -> Option<&mut QueryEnd>

If end is set, returns Some with a mutable reference to the value; otherwise returns None.

pub fn end_mut(&mut self) -> &mut QueryEnd

Returns a mutable reference to end. If the field is unset, it is first initialized with the default value.

pub fn end_opt(&self) -> Option<&QueryEnd>

If end is set, returns Some with the value; otherwise returns None.

pub fn set_end<T: Into<QueryEnd>>(&mut self, field: T)

Sets end with the provided value.
