Crate vortex_io 

Core traits and implementations for asynchronous IO.

Vortex implements an IPC streaming format as well as a file format, both of which run on top of a variety of storage systems that can be accessed from multiple async runtimes.

This crate provides core traits for positioned and streaming IO, and via feature flags implements the core traits for several common async runtimes and backing stores.

Modules

compat

Compatibility layer similar to Rust async-compat that allows non-Tokio runtimes to use Tokio-based implementations of the core traits, such as the ObjectStore implementations.

filesystem

A filesystem abstraction for discovering and opening Vortex files.

kanal_ext

object_store

runtime

A Vortex runtime provides an abstract way of scheduling mixed I/O and CPU workloads onto the various threading models supported by Vortex.

session

std_file

Structs

AsyncWriteAdapter

An adapter to use an AsyncWrite as a VortexWrite.

CoalesceConfig

Configuration for coalescing nearby I/O requests into single operations.

InstrumentedReadAt

A wrapper that instruments a VortexReadAt with metrics.

OwnedSlice

An owned view into a contiguous sequence of bytes.

SizeLimitedStream

A Stream that can work on several simultaneous requests, capping the amount of memory it uses at any given point.

Traits

IoBuf

Trait for types that can provide a readonly byte buffer interface to I/O frameworks.

VortexReadAt

The unified read trait for Vortex I/O sources.
