From the
```
impl TryFrom<SchemaAsIpc<'_>> for IpcMessage {
type Error = ArrowError;
fn try_from(schema_ipc: SchemaAsIpc) -> ArrowResult<Self> {
let pair = *schema_ipc;
// schema as data
let encoded_data = flight_schema_as_encoded_data(pair.0, pair.1);
let mut schema = vec![];
arrow::ipc::writer::write_message(&mut schema, encoded_data,
pair.1)?;
Ok(IpcMessage(schema))
}
}
```
```
impl From<SchemaAsIpc<'_>> for SchemaResult {
fn from(schema_ipc: SchemaAsIpc) -> Self {
let IpcMessage(vals) = flight_schema_as_flatbuffer(schema_ipc.0,
schema_ipc.1);
SchemaResult { schema: vals }
}
}
```
converting the schema to other type has the different implementation.
