Crate range_reader

Offers two structs:

• RangedReader, that implements std::io::Read and std::io::Seek from a function returning a Vec<u8> from a ranged request (start, length).
• RangedAsyncReader that implements [futures::io::AsyncRead] and [futures::io::AsyncRead] from a asynchronous function returning (a future of) Vec<u8> from a ranged request (start, length).

A common use use-case for this crate is to perform ranged queries from remote blob storages such as AWS s3, Azure blob, and Google’s cloud storage.

Structs

RangeOutput

A range of bytes with a known starting position.

RangedAsyncReader

A struct that converts RangedFuture to a AsyncRead + AsyncSeek with an internal buffer.

RangedReader

Implements Read + Seek for a (blocking) function that reads ranges of bytes.

Type Definitions

RangedFuture

A function that returns a [BoxFuture] of RangeOutput. For example, an async request to return a range of bytes from a blob from the internet.
