Struct libafl :: corpus :: inmemory_ondisk :: InMemoryOnDiskCorpus Copy item path

impl InMemoryOnDiskCorpus
where I: Input,

pub fn new(dir_path: P) -> Result<Self, Error>
where P: AsRef<Path>,

Creates an InMemoryOnDiskCorpus.

This corpus stores all testcases to disk, and keeps all of them in memory, as well.

By default, it stores metadata for each Testcase as prettified json. Metadata will be written to a file named .<testcase>.metadata The metadata may include objective reason, specific information for a fuzz job, and more.

If you don’t want metadata, use InMemoryOnDiskCorpus::no_meta. To pick a different metadata format, use InMemoryOnDiskCorpus::with_meta_format.

Will error, if std::fs::create_dir_all() failed for dir_path.

pub fn with_meta_format( dir_path: P, meta_format: Option<OnDiskMetadataFormat> ) -> Result<Self, Error>
where P: AsRef<Path>,

Creates the InMemoryOnDiskCorpus specifying the format in which Metadata will be saved to disk.

Will error, if std::fs::create_dir_all() failed for dir_path.

pub fn with_meta_format_and_prefix( dir_path: P, meta_format: Option<OnDiskMetadataFormat>, prefix: Option<String>, locking: bool ) -> Result<Self, Error>
where P: AsRef<Path>,

Creates the InMemoryOnDiskCorpus specifying the format in which Metadata will be saved to disk and the prefix for the filenames.

Will error, if std::fs::create_dir_all() failed for dir_path.

pub fn no_meta(dir_path: P) -> Result<Self, Error>
where P: AsRef<Path>,

Creates an InMemoryOnDiskCorpus that will not store .metadata files

Will error, if std::fs::create_dir_all() failed for dir_path.

pub fn rename_testcase( &self, testcase: &mut Testcase, filename: String ) -> Result<(), Error>

Sets the filename for a Testcase. If an error gets returned from the corpus (i.e., file exists), we’ll have to retry with a different filename.

pub fn dir_path(&self) -> &PathBuf

Path to the corpus directory associated with this corpus
