std :: sys :: io :: kernel_copy :: linux :: FdMeta

Enum `FdMeta`

pub(in ::sys::io::kernel_copy::linux) enum FdMeta

This type represents either the inferred FileType of a RawFd based on the source type from which it was extracted or the actual metadata

The methods on this type only provide hints, due to AsRawFd and FromRawFd the inferred type may be wrong.

Variants

Metadata(Metadata)
Socket
Pipe
NoneObtained: We don't have any metadata because the stat syscall failed
