Cairo bootloader\n\nCairo bootloader port for the Rust Cairo VM.\n\nThe Cairo bootloader is a Cairo program that loads and executes other programs in a provable way.\nIt is also able to execute Cairo PIEs (Position Independent Executables) along with regular Cairo programs.\n\nWe currently support Cairo bootloader v0.13.0.\n\n## How to use this library\n\nWe provide two hint processors that can be used to execute bootloader hints.\n\n### Standalone hint processor\n\nThe standalone hint processor (`BootloaderHintProcessor`) is the simplest way to execute the bootloader. \nYou can just declare the hint processor and use it in `cairo_run_program`.\n\nCheck the [run program example](./examples/run_program.rs) for more details on how to configure the bootloader options.\n\n### Minimal hint processor.\n\nFor advanced use cases, we also provide the `MinimalBootloaderHintProcessor` struct.\nThis is useful when you want to mix multiple hint processors (ex: Starknet OS hints + bootloader hints + builtin hints)\nand avoid checking for the Cairo VM hints multiple times, or simply avoid compatibility issues between different\nversions of `cairo-vm`.\n\nTo use this hint processor, you will need to define your own hint processor structure and implement the `HintProcessorLogic`\ntrait yourself.\n\nNote that this is exactly how the `BootloaderHintProcessor` struct is implemented.\n\n## Limitations\n\n* Composite packed outputs are not supported yet.\n* The bootloader is not able to load hints for Cairo 0 programs with hints yet.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstarkware-libs%2Fproving-utils","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstarkware-libs%2Fproving-utils","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstarkware-libs%2Fproving-utils/lists"}
