Neville Dipale created ARROW-5191: ------------------------------------- Summary: [Rust] Expose schema in readers (CSV, JSON) without reading batches Key: ARROW-5191 URL: https://issues.apache.org/jira/browse/ARROW-5191 Project: Apache Arrow Issue Type: Improvement Components: Rust Reporter: Neville Dipale
It's sometimes convenient to be able to view a datasource's schema without reading the first record batch. This is a proposal to create a `pub fn schema(&self) -> Arc<Schema>` on the various readers that we support. I think this would also enable schema inference in datafusion -- This message was sent by Atlassian JIRA (v7.6.3#76005)
