1//! Gemini `generateContent` / `streamGenerateContent` wire codec.
2//!
3//! Builds a Google generativeLanguage v1beta request from a
4//! [`crate::canonical::CanonicalRequest`], parses the buffered reply into
5//! a [`crate::canonical::CanonicalResponse`], and maps the SSE byte
6//! stream (`?alt=sse`) to [`crate::canonical::CanonicalEvent`]s.
7//!
8//! Gemini authenticates with an `x-goog-api-key` header (the `?key=` query
9//! param is the alternative; this codec uses the header so keys stay out of
10//! request lines and logs). The serde shapes of the Gemini bodies
11//! (`GeminiRequest`, `GeminiResponse`, …) are public so other Gemini callers —
12//! the image-generation provider — build on the same definitions.
