v0.24.0

What's Changed

libbpf-rs

• Split {Open,}{Map,Program} into {Open,}{Map,Program} (for shared access) and {Open,}{Map,Program}Mut (for exclusive access)
• Added AsRawLibbpf impl for OpenObject and ObjectBuilder
• Decoupled Map and MapHandle more and introduced MapCore trait abstracting over common functionality
• Adjusted SkelBuilder::open method to require mutable reference to storage space for BPF object
• Adjusted {Open,}Object::from_ptr constructor to be infallible
• Added {Open,}Object::maps{_mut,} and {Open,}Object::progs{_mut,} for BPF map and program iteration
• Adjusted various APIs to return/use OsStr instead of CStr or str
• Adjusted {Open,}Program to lazily retrieve name and section
  • Changed name and section methods to return &OsStr and made constructors infallible
• Adjusted OpenObject::name to return Option<&OsStr>
• Removed Result return type from OpenProgram::{set_log_level,set_autoload,set_flags}
• Added Object::name method
• Added Copy and Clone impls for types inside btf::types module
• Adjusted OpenMap::set_inner_map_fd to return Result
• Adjusted ProgramInput::context_in field to be a mutable reference
• Made inner query::Tag contents publicly accessible
• Fixed potential memory leak in RingBufferBuilder::build
• Removed Display implementation of various enum types

libbpf-cargo

• Reworked generated skeletons to contain publicly accessible maps and program members, no longer requiring method calls
• Adjusted skeleton creation logic to generate Rust types for all types available in BPF
• Renamed module for generated Rust types from <project>_types to just types
• Renamed generated struct_ops type to StructOps and moved it out of types module
• Fixed Rust code generation logic to properly create Default impl for arrays of pointers
