Struct FilteredReadPlanProto 

pub struct FilteredReadPlanProto {
    pub row_addr_tree_map: Vec<u8>,
    pub scan_range_after_filter: Option<U64Range>,
    pub filter_schema_ipc: Option<Vec<u8>>,
    pub fragment_filter_ids: HashMap<u32, u32>,
    pub filter_expressions: Vec<Vec<u8>>,
}

Serializable form of FilteredReadPlan (planned/distributed mode). RowAddrTreeMap serialized via its built-in serialize_into/deserialize_from. Per-fragment filters are Substrait-encoded and deduplicated.

Fields

row_addr_tree_map: Vec<u8>

scan_range_after_filter: Option<U64Range>

filter_schema_ipc: Option<Vec<u8>>

Arrow IPC schema for decoding Substrait filters (matches the schema used at encode time).

fragment_filter_ids: HashMap<u32, u32>

Per-fragment filter mapping. Key is fragment id, value is a list index into filter_expressions. Multiple fragments can share the same list index when they have the same filter, avoiding duplicate Substrait encoding.

filter_expressions: Vec<Vec<u8>>

Deduplicated Substrait-encoded filter expressions. Each entry is referenced by one or more values in fragment_filter_ids.

Implementations

impl FilteredReadPlanProto

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

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

Trait Implementations

impl Clone for FilteredReadPlanProto

fn clone(&self) -> FilteredReadPlanProto

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilteredReadPlanProto

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

Formats the value using the given formatter.

impl Default for FilteredReadPlanProto

fn default() -> Self

Returns the “default value” for a type.

impl Message for FilteredReadPlanProto

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 FilteredReadPlanProto

const NAME: &'static str = "FilteredReadPlanProto"

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 FilteredReadPlanProto

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