Struct TableIdentifier 

pub struct TableIdentifier {
    pub uri: String,
    pub version: u64,
    pub manifest_etag: Option<String>,
    pub serialized_manifest: Option<Vec<u8>>,
    pub storage_options: HashMap<String, String>,
}

Identifies a Lance dataset for remote reconstruction.

Two modes:

1. uri + serialized_manifest (fast): remote executor skips manifest read.
2. uri + version + etag (lightweight): remote executor loads manifest from storage.

Fields

uri: String

version: u64

manifest_etag: Option<String>

serialized_manifest: Option<Vec<u8>>

storage_options: HashMap<String, String>

Implementations

impl TableIdentifier

pub fn manifest_etag(&self) -> &str

Returns the value of manifest_etag, or the default value if manifest_etag is unset.

pub fn serialized_manifest(&self) -> &[u8]

Returns the value of serialized_manifest, or the default value if serialized_manifest is unset.

Trait Implementations

impl Clone for TableIdentifier

fn clone(&self) -> TableIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableIdentifier

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

Formats the value using the given formatter.

impl Default for TableIdentifier

fn default() -> Self

Returns the “default value” for a type.

impl Message for TableIdentifier

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl Name for TableIdentifier

const NAME: &'static str = "TableIdentifier"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "lance.datafusion"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for TableIdentifier

fn eq(&self, other: &TableIdentifier) -> 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.
