State Schema trait

Provided Methods§

Source

fn from_input(input: Self) -> Self

Create initial state from input

Source

fn to_json(&self) -> GraphResult<Value>

Get state as JSON for debugging/checkpointing.

Returns a Result instead of silently producing Value::Null (Q2): a serialization failure is data corruption in the state machine and must surface at the call site, not be swallowed.

Dyn Compatibility§

This trait is not dyn compatible.

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