Module error 

Error handling for the FFI layer.

This module defines the NemoFlowStatus enum returned by every exported FFI function, along with thread-local storage for human-readable error messages. After any non-Ok return, the caller should invoke nemo_flow_last_error on the same thread to obtain a diagnostic string. The error message remains valid until the next FFI call on that thread clears it via clear_last_error.

Enums

NemoFlowStatus

Status codes returned by all FFI functions.

Functions

clear_last_error

Clear the thread-local last-error message.

last_error_message

Retrieve the last error message set on this thread, if any.

nemo_flow_last_error

Retrieve the last error message set on this thread, or null if no error has occurred since the last clear_last_error call.

nemo_flow_set_last_error_message^⚠

Set the thread-local last-error message from foreign code.

set_last_error

Store an error message in thread-local storage for later retrieval.

status_from_error

Convert an FlowError to an NemoFlowStatus, storing the error message in thread-local storage.

status_from_plugin_error

Convert a PluginError to an NemoFlowStatus, storing the error message in thread-local storage.
