Enum IpcError 

#[non_exhaustive]
pub enum IpcError {
    Arrow(String),
    EmptyBatchInput,
    SecretLeakAttempt {
        column: String,
    },
}

Errors raised by the Arrow IPC bridge.

Both uni-plugin-extism and uni-plugin-wasm wrap this in their crate-level error enums via #[from].

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Arrow(String)

Arrow IPC encode / decode failed at the wasm boundary.

EmptyBatchInput

Called encode_batches with no input — there’s no schema to write into the stream header.

SecretLeakAttempt

FU-2: a plugin attempted to serialize a column tagged with the uni-db.secret-handle Arrow extension into its output batch. The host blocks the serialization so the opaque handle cannot leak across the wasm boundary as raw bytes.

Fields

column: String

Name of the offending column.

Trait Implementations

impl Debug for IpcError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for IpcError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for IpcError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
