Struct aws_sdk_glue::types::DropNullFields

#[non_exhaustive]
pub struct DropNullFields {
    pub name: String,
    pub inputs: Vec<String>,
    pub null_check_box_list: Option<NullCheckBoxList>,
    pub null_text_list: Option<Vec<NullValueField>>,
}

Specifies a transform that removes columns from the dataset if all values in the column are 'null'. By default, Glue Studio will recognize null objects, but some values such as empty strings, strings that are "null", -1 integers or other placeholders such as zeros, are not automatically recognized as nulls.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

The name of the transform node.

inputs: Vec<String>

The data inputs identified by their node names.

null_check_box_list: Option<NullCheckBoxList>

A structure that represents whether certain values are recognized as null values for removal.

null_text_list: Option<Vec<NullValueField>>

A structure that specifies a list of NullValueField structures that represent a custom null value such as zero or other value being used as a null placeholder unique to the dataset.

The DropNullFields transform removes custom null values only if both the value of the null placeholder and the datatype match the data.

Implementations

impl DropNullFields

pub fn name(&self) -> &str

The name of the transform node.

pub fn inputs(&self) -> &[String]

The data inputs identified by their node names.

pub fn null_check_box_list(&self) -> Option<&NullCheckBoxList>

A structure that represents whether certain values are recognized as null values for removal.

pub fn null_text_list(&self) -> &[NullValueField]

A structure that specifies a list of NullValueField structures that represent a custom null value such as zero or other value being used as a null placeholder unique to the dataset.

The DropNullFields transform removes custom null values only if both the value of the null placeholder and the datatype match the data.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .null_text_list.is_none().

impl DropNullFields

pub fn builder() -> DropNullFieldsBuilder

Creates a new builder-style object to manufacture DropNullFields.

Trait Implementations

impl Clone for DropNullFields

fn clone(&self) -> DropNullFields

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DropNullFields

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

Formats the value using the given formatter.

impl PartialEq for DropNullFields

fn eq(&self, other: &DropNullFields) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
