IpcFileHandle

zng::task::channel

Struct IpcFileHandle 

Source 
pub struct IpcFileHandle { /* private fields */ }
Expand description

File handle that can be transferred to another process.

§File

This type can be converted from and to std::fs::File. This type does not implement IO traits, it must be converted to read/write. The file handle is only closed on drop if it was not converted back.

§Serialization

This type implements serialization only for compatibility with IPC channel, attempting to serialize it outside of with_ipc_serialization context will return an error. On IPC serialization the handle is duplicated for the target process.

Implementations§

Source§

impl IpcFileHandle

Source

pub fn duplicate(&self) -> Result<IpcFileHandle, Error>

Duplicate file handle for the same process.

Note that the read/write offset is associated with the system handle, if you convert multiple duplicates to File any read in one instance advances the position in all instances.
