uefi: fs: Implement exists Also adds the initial file abstractions. The file opening algorithm is inspired from UEFI shell. It starts by classifying if the Path is Shell mapping, text representation of device path protocol, or a relative path and converts into an absolute text representation of device path protocol. After that, it queries all handles supporting EFI_SIMPLE_FILE_SYSTEM_PROTOCOL and opens the volume that matches the device path protocol prefix (similar to Windows drive). After that, it opens the file in the volume using the remaining pat. It also introduces OwnedDevicePath and BorrowedDevicePath abstractions to allow working with the base UEFI and Shell device paths efficiently. DevicePath in UEFI behaves like an a group of nodes laied out in the memory contiguously and thus can be modeled using iterators. This is an effort to break the original PR (https://github.com/rust-lang/rust/pull/129700) into much smaller chunks for faster upstreaming.
rust-analyzer is a modular compiler frontend for the Rust language. It is a part of a larger rls-2.0 effort to create excellent IDE support for Rust.
