Struct FieldOptionsCaseRule 

#[non_exhaustive]
pub struct FieldOptionsCaseRule {
    pub parent_field_id: Option<String>,
    pub child_field_id: Option<String>,
    pub parent_child_field_options_mappings: Vec<ParentChildFieldOptionsMapping>,
}

Rules that control which options are available in a child field based on the selected value in a parent field.

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.

parent_field_id: Option<String>

The identifier of the parent field that controls options.

child_field_id: Option<String>

The identifier of the child field whose options are controlled.

parent_child_field_options_mappings: Vec<ParentChildFieldOptionsMapping>

A mapping between a parent field option value and child field option values.

Implementations

impl FieldOptionsCaseRule

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

The identifier of the parent field that controls options.

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

The identifier of the child field whose options are controlled.

pub fn parent_child_field_options_mappings( &self, ) -> &[ParentChildFieldOptionsMapping]

A mapping between a parent field option value and child field option values.

impl FieldOptionsCaseRule

pub fn builder() -> FieldOptionsCaseRuleBuilder

Creates a new builder-style object to manufacture FieldOptionsCaseRule.

Trait Implementations

impl Clone for FieldOptionsCaseRule

fn clone(&self) -> FieldOptionsCaseRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldOptionsCaseRule

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

Formats the value using the given formatter.

impl PartialEq for FieldOptionsCaseRule

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