Function read_header_info

arrow-avro/src/reader/async_reader/builder.rs:125–136

Reads the Avro file header (magic, metadata, sync marker) asynchronously from `reader`. On success, returns the parsed [`HeaderInfo`] containing the header and its length in bytes.

    reader: &mut R,
    file_size: u64,
