Enum RowDatasetVersionMeta 

pub enum RowDatasetVersionMeta {
    Inline(Vec<u8>),
    External(ExternalFile),
}

Metadata about the location of dataset version sequence data Following the same pattern as RowIdMeta

Variants

Inline(Vec<u8>)

Small sequences stored inline in the fragment metadata

External(ExternalFile)

Large sequences stored in external files

Implementations

impl RowDatasetVersionMeta

pub fn from_sequence(sequence: &RowDatasetVersionSequence) -> Result<Self>

Create inline metadata from a version sequence

pub fn from_external_file(path: String, offset: u64, size: u64) -> Self

Create external metadata reference

pub fn load_sequence(&self) -> Result<RowDatasetVersionSequence>

Load the version sequence from this metadata

Trait Implementations

impl Clone for RowDatasetVersionMeta

fn clone(&self) -> RowDatasetVersionMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RowDatasetVersionMeta

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

Formats the value using the given formatter.

impl DeepSizeOf for RowDatasetVersionMeta

fn deep_size_of_children(&self, context: &mut Context) -> usize

Returns an estimation of the heap-managed storage of this object. This does not include the size of the object itself.

fn deep_size_of(&self) -> usize

Returns an estimation of a total size of memory owned by the object, including heap-managed storage.

impl<'de> Deserialize<'de> for RowDatasetVersionMeta

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RowDatasetVersionMeta

fn eq(&self, other: &RowDatasetVersionMeta) -> 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 RowDatasetVersionMeta

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<CreatedAtVersionSequence> for RowDatasetVersionMeta

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: CreatedAtVersionSequence) -> Result<Self>

Performs the conversion.

impl TryFrom<LastUpdatedAtVersionSequence> for RowDatasetVersionMeta

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: LastUpdatedAtVersionSequence) -> Result<Self>

Performs the conversion.
