impl BlkidCache

pub fn put_cache(&mut self)

Save changes to cache file

pub fn get_cache(&mut self, filename: &Path) -> Result<()>

Allocate and initalize cache handler

pub fn gc_cache(&mut self)

pub fn iter(&self) -> BlkidDevIterⓘ

Important traits for BlkidDevIter

impl Iterator for BlkidDevIter type Item = BlkidDev;

Create an iterator from the cached devices

pub fn probe_all(&mut self) -> Result<()>

Probe for all block devices

pub fn probe_all_new(&mut self) -> Result<()>

Probe for all new block devices

pub fn probe_all_removable(&mut self) -> Result<()>

pub fn get_dev(&self, devname: &str, flags: BlkidDevFlags) -> Result<BlkidDev>

Find a device by device name in the cache.

Get the value associated with a tag (e.g. TYPE) for a given device

pub fn get_devname(
    &self,
    token_or_pair: Either<&str, (&str, &str)>
) -> Result<&str>

Get the device name for a specific NAME=value tag pair in the cache

pub fn find_dev_with_tag(&self, type_: &str, value: &str) -> Result<BlkidDev>

Find the device with the specified tag
