Overview

‘TsipParser::Uri` is a TypedData wrapper around a Rust `tsip_parser::Uri`. Scalar accessors (`scheme`, `user`, …) are Rust methods defined by the native extension. This file adds the Ruby-side concerns: memoizing `params` / `headers` so mutations stick, plus serialization / equality.

PCT_ESCAPE_CHARS =

Mirror crate 0.2.1’s ‘append_pct_escaped` — used for fields that are pct-decoded on parse (userinfo, URI header key/value). Uppercase hex because re-parse re-decodes, so case doesn’t affect the fixed point.

"@:;?<>%&= \t\r\n"
PARAM_ESCAPE_CHARS =

Mirror crate 0.2.1’s ‘append_param_escaped`. URI-level params are stored literally (no pct-decode on parse), so only bytes that would re-tokenize the URI body on re-parse need escaping. `%` is NOT escaped here: the stored value already contains any `%` the user put in, and escaping `%` would turn `%3c` into `%253c` on re-render. Lowercase hex — on re-parse, `downcase_str` lowercases keys, so matching case reaches a fixed point in one cycle rather than two.

#params ⇒ Object

Materialize the params Hash lazily. Once touched, subsequent reads —and any in-place mutations — hit the cached ivar, so tsip-core-style ‘uri.params = “tls”` patterns keep working.
