Struct Parse

pub struct Parse {
    pub input: Option<Box<Relation>>,
    pub format: i32,
    pub schema: Option<DataType>,
    pub options: HashMap<String, String>,
}

Fields

input: Option<Box<Relation>>

(Required) Input relation to Parse. The input is expected to have single text column.

format: i32

(Required) The expected format of the text.

schema: Option<DataType>

(Optional) DataType representing the schema. If not set, Spark will infer the schema.

options: HashMap<String, String>

Options for the csv/json parser. The map key is case insensitive.

Implementations

impl Parse

pub fn format(&self) -> ParseFormat

Returns the enum value of format, or the default if the field is set to an invalid enum value.

pub fn set_format(&mut self, value: ParseFormat)

Sets format to the provided enum value.

Trait Implementations

impl Clone for Parse

fn clone(&self) -> Parse

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Parse

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

Formats the value using the given formatter.

impl Default for Parse

fn default() -> Self

Returns the “default value” for a type.

impl Message for Parse

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

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

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

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

impl PartialEq for Parse

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