Trait Authorizer 

pub trait Authorizer: Send + Sync {
    // Required method
    fn authorize(
        &self,
        action: AuthAction,
        arg1: Option<&str>,
        arg2: Option<&str>,
        db_name: Option<&str>,
        trigger: Option<&str>,
    ) -> AuthResult;
}

Statement authorizer callback (§9.4).

Called during SQL compilation (not execution) to approve or deny each operation. Used for sandboxing untrusted SQL.

Parameters

• action: The type of SQL operation being authorized.
• arg1/arg2: Context-dependent string parameters (table name, column name, index name, etc.). The meaning depends on the AuthAction.
• db_name: The database name (e.g. "main", "temp", attached name).
• trigger: If the operation originates inside a trigger, this is the trigger name. None for top-level SQL.

Required Methods

fn authorize( &self, action: AuthAction, arg1: Option<&str>, arg2: Option<&str>, db_name: Option<&str>, trigger: Option<&str>, ) -> AuthResult

Return allow/deny/ignore for the given action.

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
