Struct FilteredReadExecProto 

pub struct FilteredReadExecProto {
    pub table: Option<TableIdentifier>,
    pub options: Option<FilteredReadOptionsProto>,
    pub plan: Option<FilteredReadPlanProto>,
}

Top-level wrapper for FilteredReadExec serialization.

Fields

table: Option<TableIdentifier>

options: Option<FilteredReadOptionsProto>

plan: Option<FilteredReadPlanProto>

FilteredRead has two modes Plan-then-execute (distributed): The planner creates a FilteredReadPlan and sends it to a remote executor. Plan-and-execute (local): The executor creates the plan itself at execution time.

Note: FilteredReadExec.index_input (child ExecutionPlan) is NOT serialized here. DataFusion’s PhysicalExtensionCodec handles child plans automatically: it walks the plan tree via children() / with_new_children(), serializes each node, and passes deserialized children back as the inputs parameter in try_decode. This means any ExecutionPlan in the tree (including index_input) must also implement try_encode/try_decode in the PhysicalExtensionCodec. TODO: implement serialize/deserialize for lance-specific index input ExecutionPlans.

Trait Implementations

impl Clone for FilteredReadExecProto

fn clone(&self) -> FilteredReadExecProto

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilteredReadExecProto

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

Formats the value using the given formatter.

impl Default for FilteredReadExecProto

fn default() -> Self

Returns the “default value” for a type.

impl Message for FilteredReadExecProto

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 FilteredReadExecProto

const NAME: &'static str = "FilteredReadExecProto"

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 FilteredReadExecProto

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