Struct WorkflowList 

pub struct WorkflowList { /* private fields */ }

The workflow table as it accumulates pages.

Infinite scroll appends pages; a refresh or a new query replaces them. Two properties have to hold no matter which happened:

• Sorted newest-first. The server does not order ListWorkflowExecutions, and the dev server’s standard visibility store rejects ORDER BY outright, so the ordering is this type’s job rather than the query’s.
• No duplicates. Pages are snapshots of a set that is changing underneath them, so the same execution can legitimately arrive on two pages. A table that shows a workflow twice makes the operator doubt the whole screen.

Implementations

impl WorkflowList

pub fn rows(&self) -> &[WorkflowRow]

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn tokens(&self) -> &[(String, Vec<u8>)]

Per-namespace continuation tokens to send with the next page request.

pub fn has_more(&self) -> bool

Whether any namespace still has pages left.

pub fn reset(&mut self, rows: Vec<WorkflowRow>, tokens: Vec<(String, Vec<u8>)>)

Start over: a new query, or a refresh of the current one.

pub fn append(&mut self, rows: Vec<WorkflowRow>, tokens: Vec<(String, Vec<u8>)>)

Add the next page.

pub fn position_of(&self, key: (&str, &str)) -> Option<usize>

Where the row with this key sits now, if it is still listed.
