Struct argdata::fd::EncodedFd

pub struct EncodedFd<T> { /* fields omitted */ }

A file descriptor in some argdata.

Methods

impl<T: ConvertFd> EncodedFd<T>

pub fn new(raw: u32, convert_fd: T) -> EncodedFd<T>

Create an EncodedFd that will convert raw to an Fd using convert_fd.

pub fn raw_encoded_number(&self) -> u32

The 32-bit file descriptor number exactly as encoded in the raw argdata.

pub fn to_fd(&self) -> Result<Fd, u32>

Converts this to a valid file descriptor, if possible.

On failure, the raw encoded number is returned as an error.

Trait Implementations
