Module cursor 

Cursor-based pagination for event queries.

This module provides GraphQL-style cursor pagination for efficiently querying large sets of events. It uses keyset pagination for stable, efficient results.

Key Types

• Value - Base64-encoded cursor string
• Args - Pagination arguments (first/after, last/before)
• ReadResult - Paginated result with edges and page info
• Reader - In-memory pagination executor

Example

use evento::cursor::{Args, Reader};

// Forward pagination: first 10 events
let args = Args::forward(10, None);

// Continue from cursor
let args = Args::forward(10, Some(page_info.end_cursor));

// Backward pagination: last 10 events before cursor
let args = Args::backward(10, Some(cursor));

// In-memory pagination
let result = Reader::new(events)
    .forward(10, None)
    .execute()?;
