In-Memory Data (VecDataSource)#

#Overview

VecDataSource is the simplest data source — a Vec<RowRecord> stored entirely in memory.

#Creating

use rs_grid_core::{datasource::VecDataSource, row::RowRecord};

let rows: Vec<RowRecord> = (0..1000).map(|i| {
    let mut r = RowRecord::new(i);
    r.set("name", format!("User {i}"));
    r.set("email", format!("user{i}@example.com"));
    r
}).collect();

let data = VecDataSource::new(rows);

Or use the shorthand GridModel::new() which wraps a Vec<RowRecord> in a VecDataSource automatically:

let model = GridModel::new(columns, rows, 32.0, 36.0);

#Properties

#When to use

• Datasets up to ~100,000 rows
• Mutable data (direct editing without the patches layer)
• When you need to clone the data source

#When NOT to use

• Very large datasets (millions of rows) — use FnDataSource instead
• Server-side data — use PageCacheDataSource
