Struct FdTarget 

pub struct FdTarget {
    pub dev: u64,
    pub ino: u64,
    pub rdev: u64,
}

Identity of whatever a file descriptor points at.

Fields

dev: u64

The device holding the file (st_dev).

ino: u64

The inode number (st_ino).

rdev: u64

For a device node, the device it stands for (st_rdev); 0 otherwise.

Implementations

impl FdTarget

pub fn from_fd(fd: impl AsFd) -> Result<Self>

Inspect an open file descriptor.

pub fn from_path(path: &str) -> Result<Self>

Inspect a path (following symlinks).

pub fn is_dev_null(&self) -> bool

True when this is /dev/null: the same inode, or the same (non-zero) device number. False when /dev/null cannot be inspected.
