Struct SelectionValue 

pub struct SelectionValue {
    pub items: IndexSet<SelectionItem>,
    pub provenance: Provenance,
}

An observed selection value.

Stored as an IndexSet so duplicates are impossible and authored order is preserved. Canonical form sorts items lexicographically before hashing so two selections that differ only in authored order fingerprint the same.

Fields

items: IndexSet<SelectionItem>

The selected items, in authored order.

provenance: Provenance

Shared provenance.

Implementations

impl SelectionValue

pub fn new( name: ParameterName, items: IndexSet<SelectionItem>, generator: Option<GeneratorInfo>, ) -> Self

Construct, computing the fingerprint and stamping “now”.

pub fn new_at( name: ParameterName, items: IndexSet<SelectionItem>, generator: Option<GeneratorInfo>, now: Timestamp, ) -> Self

Construct with an explicit timestamp.

pub fn fingerprint_of( name: &ParameterName, items: &IndexSet<SelectionItem>, ) -> Fingerprint

Canonical fingerprint for a selection value. Items sort lexicographically by UTF-8 bytes before hashing.

Trait Implementations

impl Clone for SelectionValue

fn clone(&self) -> SelectionValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SelectionValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SelectionValue

fn eq(&self, other: &SelectionValue) -> 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 SelectionValue

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SelectionValue
