Expand description

Lance Namespace error type.

This enum provides fine-grained error types for Lance Namespace operations. Each variant corresponds to a specific error condition and has an associated ErrorCode accessible via the code() method.

§Converting to lance_core::Error

NamespaceError implements Into<lance_core::Error>, preserving the original error so it can be downcast later:

ⓘ
let ns_err = NamespaceError::TableNotFound { message: "...".into() };
let lance_err: lance_core::Error = ns_err.into();

// Later, extract the original error:
if let lance_core::Error::Namespace { source, .. } = &lance_err {
    if let Some(ns_err) = source.downcast_ref::<NamespaceError>() {
        println!("Error code: {:?}", ns_err.code());
    }
}

Implementations§

Source§

impl NamespaceError

Source

pub fn code(&self) -> ErrorCode

Returns the error code for this error.

Use this for programmatic error handling across language boundaries.

Source

pub fn from_code(code: u32, message: impl Into<String>) -> Self

Creates a NamespaceError from an error code and message.

This is useful when receiving errors from REST API or other language bindings.
