Struct DatasetManifest 

pub struct DatasetManifest {
    pub version: u32,
    pub entries: Vec<FileReceipt>,
}

JSON manifest containing the files associated with one dataset operation.

Fields

version: u32

Version of the manifest JSON schema.

entries: Vec<FileReceipt>

File and URI receipts in operation order.

Implementations

impl DatasetManifest

pub const fn new() -> DatasetManifest

Creates an empty manifest at the current schema version.

pub fn add_file( &mut self, role: ReceiptRole, path: impl AsRef<Path>, ) -> Result<(), IoError>

Adds a checksummed local file receipt.

pub fn add_uri(&mut self, role: ReceiptRole, uri: impl Into<PathBuf>)

Adds a URI receipt without claiming a local byte count or checksum.

pub fn read_json(path: impl AsRef<Path>) -> Result<DatasetManifest, IoError>

Reads a JSON manifest from disk without trusting its file receipts.

pub fn validate_local_files(&self) -> Result<ManifestValidation, IoError>

Re-hashes local entries and rejects missing, changed, or partial receipts.

pub fn to_json(&self) -> Result<String, IoError>

Serializes this manifest as pretty-printed JSON.

pub fn write_json(&self, path: impl AsRef<Path>) -> Result<(), IoError>

Writes this manifest as JSON, creating its parent directory if needed.

Trait Implementations

impl Clone for DatasetManifest

fn clone(&self) -> DatasetManifest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DatasetManifest

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

Formats the value using the given formatter.

impl Default for DatasetManifest

fn default() -> DatasetManifest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DatasetManifest

fn deserialize<__D>( __deserializer: __D, ) -> Result<DatasetManifest, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DatasetManifest

fn eq(&self, other: &DatasetManifest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DatasetManifest

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
