fn load_file(path: &str) -> io::Result<(NewcBuilder, File)> {
	let builder = NewcBuilder::new(path)
		.uid(1000)
		.gid(1000)
		.mode(0o100644);
		
	File::open(path)
		.map(|fp| (builder, fp))
}

source

pub fn ino(self, ino: u32) -> Self

Set the inode number for this file. In modern times however, typically this is just a a unique index ID for the file, rather than the actual inode number.

source

pub fn mode(self, mode: u32) -> Self

Set the file’s “mode” - the same as an inode “mode” field - containing permission bits and a bit of metadata about the type of file represented.

pub fn nlink(self, nlink: u32) -> Self

Set the number of links associated with this file.

source

pub fn mtime(self, mtime: u32) -> Self

Set the modification time of this file.

source

pub fn dev_major(self, dev_major: u32) -> Self

Set the major component of the device ID, describing the device on which this file resides.

Device IDs are comprised of a major and minor component. The major component identifies the class of device, while the minor component identifies a specific device of that class.

source

pub fn dev_minor(self, dev_minor: u32) -> Self

Set the minor component of the device ID, describing the device on which this file resides.

Device IDs are comprised of a major and minor component. The major component identifies the class of device, while the minor component identifies a specific device of that class.

source

pub fn rdev_major(self, rdev_major: u32) -> Self

Set the major component of the rdev ID, describes the device that this file (inode) represents.

Device IDs are comprised of a major and minor component. The major component identifies the class of device, while the minor component identifies a specific device of that class.

source

pub fn rdev_minor(self, rdev_minor: u32) -> Self

Set the minor component of the rdev ID, field describes the device that this file (inode) represents.
