Struct smartnoise_runtime::proto::Materialize

pub struct Materialize {
    pub public: bool,
    pub skip_row: bool,
    pub file_path: String,
}

Materialize Component

Load a tabular frame from a data source

This struct represents an abstract computation. Arguments are provided via the graph. Additional options are set via the fields on this struct. The return is the result of the materialize on the arguments.

Arguments

• column_names - Array

Returns

• Value - Dataframe

Fields

public: bool

skip_row: bool

when set, skip the first line (header) in a csv

file_path: String

Path to the file on the system.

Trait Implementations

impl Clone for Materialize

pub fn clone(&self) -> Materialize

    node_id: u32
) -> Result<Warnable<ValueProperties>, Error>

Given properties known about private arguments, and public arguments, derive properties about the resulting data.

impl Debug for Materialize

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

Formats the value using the given formatter.

impl Default for Materialize

pub fn default() -> Materialize

Returns the “default value” for a type.

impl Evaluable for Materialize

fn evaluate(
    &self,
    _privacy_definition: &Option<PrivacyDefinition>,
    arguments: NodeArguments
) -> Result<ReleaseNode>

The concrete implementation of the abstract computation that the struct represents.

impl Message for Materialize

pub fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

pub fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,

) -> Result<(), DecodeError> where
    B: Buf, 

pub fn encoded_len(&self) -> usize

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

pub fn clear(&mut self)

Clears the message, resetting all fields to their default.

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

Encodes the message to a buffer.

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

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

pub fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes an instance of the message from a buffer.

pub fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

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

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

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

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

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