Crate compio_driver

The platform-specified driver. Some types differ by compilation target.

Modules

• op
  The async operations. Types in this mod represents the low-level operations passed to kernel. The operation itself doesn’t perform anything. You need to pass them to crate::Proactor, and poll the driver.

Structs

• AsyncifyPool
  A thread pool to perform blocking operations in other threads.
• DispatchError
  An error that may be emitted when all worker threads are busy. It simply returns the dispatchable value with a convenient fmt::Debug and fmt::Display implementation.
• Key
  A typed wrapper for key of Ops submitted into driver. It doesn’t free the inner on dropping. Instead, the memory is managed by the proactor. The inner is only freed when:
• NotifyHandle
  A notify handle to the inner driver.
• OwnedFd
  An owned file descriptor.
• Proactor
  Low-level actions of completion-based IO. It owns the operations to keep the driver safe.
• ProactorBuilder
  Builder for Proactor.
• SharedFd
  A shared fd. It is passed to the operations to make sure the fd won’t be closed before the operations complete.
• WaitArg
  Meta of polling operations.

Enums

• Decision
  Result of OpCode::pre_submit.
• PushEntry
  The return type of Proactor::push.

Traits

• AsRawFd
  A trait to extract the raw file descriptor from an underlying object.
• Dispatchable
  A trait for dispatching a closure. It’s implemented for all `FnOnce() + Send
• OpCode
  Abstraction of operations.
• ToSharedFd
  Get a clone of SharedFd.

Type Aliases

• RawFd
  Raw file descriptors.
