Module error 

Lance Namespace error types.

This module defines fine-grained error types for Lance Namespace operations. Each error type has a unique numeric code that is consistent across all Lance Namespace implementations (Python, Java, Rust, REST).

Error Handling

Namespace operations return NamespaceError which can be converted to lance_core::Error for integration with the Lance ecosystem.

use lance_namespace::{NamespaceError, ErrorCode};

// Create and use namespace errors
let err = NamespaceError::TableNotFound {
    message: "Table 'users' not found".into(),
};
assert_eq!(err.code(), ErrorCode::TableNotFound);

// Convert to lance_core::Error
let lance_err: lance_core::Error = err.into();
