Struct GraphGeneratableEffect 

pub struct GraphGeneratableEffect<T, E, L> {
    pub value: Option<T>,
    pub error: Option<E>,
    pub logs: L,
}

The core effect type for the HKT generative system.

This struct wraps computation results in a monadic context that tracks:

• The result value (or None if an error occurred)
• Any error that prevented computation
• A complete audit log of all operations

Type Parameters

• T: The wrapped value type
• E: The error type (fixed to ModelValidationError in practice)
• L: The log type (fixed to ModificationLog in practice)

Design

The value field is Option<T> rather than T to allow representing error states without requiring T: Default. When an error occurs during a monadic operation, the value becomes None and the error is captured.

Fields

value: Option<T>

The computation result, or None if an error occurred

error: Option<E>

Any error that occurred during computation

logs: L

Complete audit trail of all operations
