Errors

A call can fail because a definition is missing, a document is invalid, or the database refuses a change. The examples use the people data to show these results. Use the status and diagnostic fields to identify the failure.

Binding errors

Language	Failure
C	Returns a status. The owner that its operation names holds the diagnostic.
Go	Returns `*Error`.
Rust	Returns `Result<_, Error>`.
Clojure	Throws `clojure.lang.ExceptionInfo` with diagnostic data.
Python	Raises `StardustError`.
Odin	Returns an `Error` beside its result.

The error record gives the fields in your language. Statuses gives the failure conditions of each operation.

error

This record describes a failure with its status and diagnostic. The binding copies the diagnostic before it releases the native owner.

Field	Type	Unit	Absent
`code`	`str`	None	—
`message`	`str`	None	—
`path`	`str \| None`	None	None
`field`	`str \| None`	None	None
`entity`	`int \| None`	None	None
`offset`	`int \| None`	Bytes	None
`status`	`str`	None	—

Statuses

Each status names a class of failure. The table lists codes from the binding. Native diagnostic codes can differ.
