This example demonstrates how to deserialize JSON responses from the CanLII legal database into strongly typed Rust structs using the `serde` and `serde_json` libraries, with `serde_derive` providing automatic trait implementations. It defines nested structures for search results, cases, legislation, and case identifiers, using attributes like `#[serde(rename)]` and `#[serde(skip_serializing_if)]` to handle API naming conventions and optional fields. The `main` function parses sample JSON payloads—including a large search response with over 1.6 million results—and prints selected fields to verify the deserialization works correctly.

Rust code shared from the playground

This example demonstrates Rust structs that model a search response with optional legislation and case results. The code uses the `serde` and `serde_derive` crates to derive `Serialize` and `Deserialize` traits, enabling JSON parsing through `serde_json::Value`. It defines nested types like `SearchResponse`, `Result`, `LegislationResult`, and `CaseResult`, with `#[serde(skip_serializing_if)]` and `#[serde(rename)]` attributes to control serialization behavior. The `main` function currently prints a placeholder message, indicating the data structures are ready for use but not yet processed.

This example shows how the Rust programming language handles tuples, structs, and custom formatting through a series of exercises from the Rust by Example tutorial. It demonstrates tuple indexing, destructuring, and reversal, plus a Matrix tuple struct with a custom `fmt::Display` implementation that prints it as a two-line grid. It also defines Point and Rectangle structs, computes rectangle area via destructuring, and creates a square from a point and side length. The code uses Rust’s standard `std::fmt` module and the `#[derive(Debug)]` attribute for debug output.

Code shared from the Rust Playground

The visualization examines Rust’s borrow checker through a small struct and its lifetime-bound methods. It shows how `bind_lifetime_mut` returns a reference to an `i32` field, while `legal` and `not_legal` illustrate differing lifetime outcomes based on control flow. The code uses Rust’s native borrow-checking rules rather than any external library, with the rendering approach being the source code itself from the Rust Playground. The example contrasts a direct return of a reborrowed reference against a conditional return that triggers an error.

This example demonstrates how to query JSONB data directly in PostgreSQL and flatten it into a relational result set. The code creates a table with a JSONB column, inserts two sample rows, and then uses two different query approaches: the `->>` operator to extract scalar fields as text, and the `jsonb_to_record` function with a column definition list to cast JSON values into typed columns (text and integer). The example highlights both methods for accessing nested JSON data, showing the explicit extraction syntax versus the more structured record-expansion technique, all within a single SQL file.

A brief introduction to JSONiq for NashFP

This example demonstrates the JSONiq query language by showing code snippets for tasks like object navigation, FLWOR expressions, JSON-to-XML conversion, and the Luhn algorithm. The sample queries use JSONiq’s map operator, function libraries like `fn:upper-case` and `fn:fold-left`, and the `keys()` and `members()` functions. Each snippet includes a link to run it in the Zorba engine’s online sandbox, referencing the NashFP presentation context.

This example documents a team investigation into using the Rust programming language for the Raspberry Pi Pico W microcontroller, outlining a migration away from C and Python. The associated image shows `picoRust.md`, a markdown file that structures the research, including a theoretical framework justifying Rust, ten hands-on practices covering compilation and flashing, and notes on toolchains and hardware debugging with OpenOCD. The visualization itself is a plain text file rendered in a browser, showing no code libraries or APIs beyond the markdown syntax and GitHub’s standard interface elements.

This example demonstrates a SQL Server stored procedure that parses incoming JSON data and inserts it into a relational table. It shows how to use the `OPENJSON` function with an explicit schema definition to extract key-value pairs, mapping the JSON’s `Key` and `Value` fields into corresponding integer and varchar columns. The procedure accepts an `nvarchar(max)` parameter for the JSON payload, making it reusable for dynamic data ingestion. The visualization highlights the transformation from a semi-structured JSON format into a normalized table structure, emphasizing the schema-mapping capabilities of T-SQL’s JSON support.

This example logs a shuffled array and fetches JSON data from a Dallas News data store containing Cowboys draft history. Using jQuery for DOM readiness and Lodash's `shuffle`, it imports a custom `getdata` module that relies on `d3-fetch`'s `json` function to asynchronously retrieve the dataset and output it to the console. The code also demonstrates commented-out alternatives with jQuery's `$.getJSON`, showing a work-in-progress approach to loading and logging the same external JSON resource.
