## When to Use What
@@ -40,19 +40,22 @@ flowchart TD
- You want to write `obj["key"]` and have it just work
- JSON files are reasonably sized (but you still want decent performance)
- You care about getting things done
+- You need full document validation upfront
### Use **SimdJSON On-Demand** when:
- Performance is critical and your data fits in memory
- You can work with forward-only traversal (no random access or backtracking)
- You need maximum speed but still want a usable API
- Your JSON structure is consistent and you control both generation and parsing
+- You're okay with partial validation (only validates parts you actually access)
+- Your JSON keys don't contain escape sequences (OnDemand matches raw keys without unescaping)
### Use **WeaselJSON** when:
- You absolutely cannot load the whole JSON into memory
- You're processing huge JSON files (multiple gigabytes)
- You want to parse just part of a JSON file without reading the rest
- You need to convert JSON into some other format as you parse it
-- You can't risk accidentally slow performance
+- You need predictable performance characteristics
- Writing stateful callbacks is your idea of fun
## The Reality

- No memory allocations during parsing
- O(1) memory usage regardless of input size
- Streaming API - no need to buffer the entire document in memory. Parsing is resumed when more data is available
-- Strings are unescaped in place before they're presented. No unicode normalization is performed
+- Strings are unescaped in place before they're presented (modifies your input buffer unless WeaselJsonRaw flag is used). No unicode normalization is performed
- Robust to crashes with untrusted input
