Struct Chunking 

pub struct Chunking {
    pub(crate) metadata_size: u64,
    pub(crate) remainder: Chunk,
    pub(crate) chunks: Vec<Chunk>,
    pub(crate) max: u32,
    processed_mapping: bool,
    pub(crate) n_provided_components: u32,
    pub(crate) n_sized_components: u32,
}

How to split up an ostree commit into “chunks” - designed to map to container image layers.

Fields

metadata_size: u64

remainder: Chunk

chunks: Vec<Chunk>

max: u32

processed_mapping: bool

n_provided_components: u32

Number of components (e.g. packages) provided originally

n_sized_components: u32

The above, but only ones with non-zero size

Implementations

impl Chunking

fn create_content_id_map( map: &IndexMap<String, ContentID>, ) -> IndexMap<ContentID, Vec<&String>>

Creates a reverse map from content IDs to checksums

pub fn new(repo: &Repo, rev: &str) -> Result<Self>

Generate an initial single chunk.

pub fn from_mapping( repo: &Repo, rev: &str, meta: &ObjectMetaSized, max_layers: &Option<NonZeroU32>, prior_build_metadata: Option<&ImageManifest>, specific_contentmeta: Option<&BTreeMap<ContentID, Vec<(Utf8PathBuf, String)>>>, ) -> Result<Self>

Generate a chunking from an object mapping.

fn remaining(&self) -> u32

pub fn process_mapping( &mut self, meta: &ObjectMetaSized, max_layers: &Option<NonZeroU32>, prior_build_metadata: Option<&ImageManifest>, specific_contentmeta: Option<&BTreeMap<ContentID, Vec<(Utf8PathBuf, String)>>>, ) -> Result<()>

Given metadata about which objects are owned by a particular content source, generate chunks that group together those objects.

pub(crate) fn take_chunks(&mut self) -> Vec<Chunk>

pub fn print(&self)

Print information about chunking to standard output.

Trait Implementations

impl Debug for Chunking

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Chunking

fn default() -> Chunking

Returns the “default value” for a type.
