sim-lib-net-core

sim-lib-net-core is a side-effect-free parser set for web-facing SIM libraries. It parses URLs, HTTP response heads, body delivery modes, chunked-transfer bodies, capped lines, SSE events, NDJSON records, and small text encodings used by shared wire formats.

The crate opens no sockets, performs no TLS, retries nothing, and attaches no application policy to the bytes it parses. Callers own transport, credentials, timeouts, and event meaning.

What it provides

• URL parsing for HTTP, HTTPS, WebSocket, and scheme-specific callers.
• HTTP request-head construction and response-head parsing.
• Body-mode classification for content length, chunked transfer, and EOF bodies.
• Bounded streaming line framing with partial-line buffering.
• Bounded SSE and NDJSON decoders for incremental service responses.
• Build-time cookbook recipe embedding for the crate's network parsing lesson.

Example

use sim_lib_net_core::LineDecoder;

let mut decoder = LineDecoder::new();
assert_eq!(decoder.push_checked(b"one\nt").unwrap(), vec![b"one".to_vec()]);
assert_eq!(decoder.push_checked(b"wo\n").unwrap(), vec![b"two".to_vec()]);

Recipes, Docs, And Validation

The recipes/ directory includes a response-head walkthrough that surfaces can show through the SIM cookbook. Rustdoc examples cover the low-level parser contracts.
