Struct SelectionParameter 

pub struct SelectionParameter {
    pub name: ParameterName,
    pub domain: SelectionDomain,
    pub constraints: Vec<SelectionConstraint>,
    pub default: Option<IndexSet<SelectionItem>>,
    pub labels: Labels,
    pub tags: Tags,
}

A parameter whose value is an ordered multi-item selection.

Fields

name: ParameterName

Parameter name.

domain: SelectionDomain

Value domain (inline values or an external resolver).

constraints: Vec<SelectionConstraint>

Registered constraints.

default: Option<IndexSet<SelectionItem>>

Optional default selection (must be a subset of the domain).

labels: Labels

Intrinsic facts.

tags: Tags

Organisational tags.

Implementations

impl SelectionParameter

pub fn of( name: ParameterName, values: IndexSet<SelectionItem>, max_selections: u32, ) -> Result<Self>

Construct a parameter backed by an inline value set.

pub fn external( name: ParameterName, resolver: ResolverId, max_selections: u32, ) -> Result<Self>

Construct a parameter backed by an external resolver.

pub fn with_default(self, default: IndexSet<SelectionItem>) -> Result<Self>

Set the default selection.

pub fn with_constraint(self, c: SelectionConstraint) -> Self

Append a constraint.

pub fn with_label(self, key: LabelKey, value: LabelValue) -> Result<Self>

Add a label.

pub fn with_tag(self, key: TagKey, value: TagValue) -> Result<Self>

Add a tag.

Trait Implementations

impl Attributed for SelectionParameter

fn labels(&self) -> &Labels

Intrinsic facts.

fn tags(&self) -> &Tags

Extrinsic organisation.

impl Clone for SelectionParameter

fn clone(&self) -> SelectionParameter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionParameter

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SelectionParameter

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SelectionParameter

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

impl Serialize for SelectionParameter

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
