pub trait MetadataSuffixFetch: MetadataFetch {
// Required method
fn fetch_suffix(&mut self, suffix: usize) -> BoxFuture<'_, Result<Bytes>>;
}Expand description
A data source that can be used with MetadataLoader to load ParquetMetaData via suffix
requests, without knowing the file size
Required Methods§
Sourcefn fetch_suffix(&mut self, suffix: usize) -> BoxFuture<'_, Result<Bytes>>
fn fetch_suffix(&mut self, suffix: usize) -> BoxFuture<'_, Result<Bytes>>
Return a future that fetches the last n bytes asynchronously
Note the returned type is a boxed future, often created by [FutureExt::boxed]. See the trait documentation for an example
