Crate libblkid_rs

libblkid-rs

libblkid_rs provides programmatic access in Rust to the C library libblkid.

Design

The organization of the modules reflects the organization of the modules in the C library. The main goal of this library is to maintain the same general structure while taking advantage of Rust idioms.

List of methods modified

• blkid_devno_to_wholedisk - This bindings method handles the buffer internally and therefore does not require a buffer argument. The limit for the maximum size of the returned device name is 4096 bytes. Please open an issue if more characters are required.
• blkid_get_dev_size - This method takes a &Path in the bindings and provides libblkid with the desired file descriptor.

List of methods not included

• blkid_verify - This method is not included because the struct flag that will notify the caller of whether it succeeded or not cannot be accessed from the public API.

Re-exports

evaluate_tag	Find the path of a device matching a tag
get_library_version	Get library version
get_partition_name	Get the name of a partition type at the given index in the libblkid internal state.
get_superblock_name	Get the name and flags of a superblock at the given index in the libblkid internal state.
