Struct aws_sdk_databrew::types::ConditionExpression

#[non_exhaustive]
pub struct ConditionExpression {
    pub condition: String,
    pub value: Option<String>,
    pub target_column: String,
}

Represents an individual condition that evaluates to true or false.

Conditions are used with recipe actions. The action is only performed for column values where the condition evaluates to true.

If a recipe requires more than one condition, then the recipe must specify multiple ConditionExpression elements. Each condition is applied to the rows in a dataset first, before the recipe action is performed.

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.

condition: String

A specific condition to apply to a recipe action. For more information, see Recipe structure in the Glue DataBrew Developer Guide.

value: Option<String>

A value that the condition must evaluate to for the condition to succeed.

target_column: String

A column to apply this condition to.

Implementations

impl ConditionExpression

pub fn condition(&self) -> &str

A specific condition to apply to a recipe action. For more information, see Recipe structure in the Glue DataBrew Developer Guide.

pub fn value(&self) -> Option<&str>

A value that the condition must evaluate to for the condition to succeed.

pub fn target_column(&self) -> &str

A column to apply this condition to.

impl ConditionExpression

pub fn builder() -> ConditionExpressionBuilder

Creates a new builder-style object to manufacture ConditionExpression.

Trait Implementations

impl Clone for ConditionExpression

fn clone(&self) -> ConditionExpression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConditionExpression

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

Formats the value using the given formatter.

impl PartialEq for ConditionExpression

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