Shared

The shared crate contains the API boundary types used by both backend and frontend.

Both crates depend on shared, so serialization mismatches between the API and the frontend are caught at compile time rather than at runtime.

Types

#![allow(unused)]
fn main() {
pub struct ApiResponse<T> {
    pub success: bool,
    pub data: Option<T>,
    pub error: Option<String>,
}

pub struct HelloResponse {
    pub message: String,
}

pub struct StatusResponse {
    pub version: String,
    pub uptime_seconds: u64,
}
}

Design notes

• Types do not use #[serde(deny_unknown_fields)] — unknown fields are silently ignored, which ensures forward compatibility as the API evolves
• Compile-time assertions verify that all types implement Serialize and Deserialize
