![]() UEFI paths can be of 4 types: 1. Absolute Shell Path: Uses shell mappings 2. Absolute Device Path: this is what we want 3: Relative root: path relative to the current root. 4: Relative Absolute shell path can be identified with `:` and Absolute Device path can be identified with `/`. Relative root path will start with `\`. The algorithm is mostly taken from edk2 UEFI shell implementation and is somewhat simple. Check for the path type in order. For Absolute Shell path, use `EFI_SHELL->GetDevicePathFromMap` to get a BorrowedDevicePath for the volume. For Relative paths, we use the current working directory to construct the new path. BorrowedDevicePath abstraction is needed to interact with `EFI_SHELL->GetDevicePathFromMap` which returns a Device Path Protocol with the lifetime of UEFI shell. Absolute Shell paths cannot exist if UEFI shell is missing. Signed-off-by: Ayush Singh <ayush@beagleboard.org> |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
