Struct Context 

pub struct Context {
    pub input: Map<String, Value>,
    pub data: Option<Value>,
    pub user: Option<AuthenticatedUser>,
    pub pool: PgPool,
    pub headers: HashMap<String, String>,
    pub response_headers: Vec<(String, String)>,
}

Context passed to controller functions for synchronous in-request business logic.

Controllers receive a mutable Context and can:

• Modify input before the DB operation (before-controllers)
• Read/modify data after the DB operation (after-controllers)
• Return Err(...) to halt the request with an error response

Example

pub async fn validate_org(ctx: &mut Context) -> Result<(), ShaperailError> {
    if let Some(email) = ctx.input.get("email").and_then(|v| v.as_str()) {
        ctx.input["email"] = serde_json::json!(email.to_lowercase());
    }
    Ok(())
}

Fields

input: Map<String, Value>

Mutable input data. Before-controllers can modify what gets written to DB.

data: Option<Value>

DB result data. None in before-controllers, Some(...) in after-controllers.

user: Option<AuthenticatedUser>

The authenticated user, if present.

pool: PgPool

Database pool for custom queries within the controller.

headers: HashMap<String, String>

Request headers (read-only).

response_headers: Vec<(String, String)>

Extra response headers the controller wants to add.
