systemprompt-wire 0.63.0

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