Struct NaDrop

pub struct NaDrop {
    pub input: Option<Box<Relation>>,
    pub cols: Vec<String>,
    pub min_non_nulls: Option<i32>,
}

Drop rows containing null values. It will invoke ‘Dataset.na.drop’ (same as ‘DataFrameNaFunctions.drop’) to compute the results.

Fields

input: Option<Box<Relation>>

(Required) The input relation.

cols: Vec<String>

(Optional) Optional list of column names to consider.

When it is empty, all the columns in the input relation will be considered.

min_non_nulls: Option<i32>

(Optional) The minimum number of non-null and non-NaN values required to keep.

When not set, it is equivalent to the number of considered columns, which means a row will be kept only if all columns are non-null.

‘how’ options (‘all’, ‘any’) can be easily converted to this field:

• ‘all’ -> set ‘min_non_nulls’ 1;
• ‘any’ -> keep ‘min_non_nulls’ unset;

Implementations

impl NaDrop

pub fn min_non_nulls(&self) -> i32

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

Trait Implementations

impl Clone for NaDrop

fn clone(&self) -> NaDrop

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NaDrop

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

Formats the value using the given formatter.

impl Default for NaDrop

fn default() -> Self

Returns the “default value” for a type.

impl Message for NaDrop

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 NaDrop

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