Struct TagKey 

pub struct TagKey {
    pub axis: TaxonomyAxis,
    pub key: String,
}

(axis, key) half of an axis-prefixed tag. Used by Predicate variants that match on the key without the value (e.g. Predicate::Exists(TagKey)).

Display form is the same as the axis-presence tag: <axis>.<key> (e.g. hardware.gpu for TagKey { axis: Hardware, key: "gpu" }).

Fields

axis: TaxonomyAxis

Taxonomy axis the key belongs to.

key: String

Key portion after the <axis>. prefix (e.g. gpu.vram_gb).

Implementations

impl TagKey

pub fn new(axis: TaxonomyAxis, key: impl Into<String>) -> TagKey

Build a TagKey from (axis, key). The key is stored verbatim; callers are responsible for choosing a stable canonical form.

Trait Implementations

impl Clone for TagKey

fn clone(&self) -> TagKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TagKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TagKey

fn deserialize<__D>( __deserializer: __D, ) -> Result<TagKey, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TagKey

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

Formats the value using the given formatter.

impl Eq for TagKey

impl Hash for TagKey

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TagKey

fn cmp(&self, other: &TagKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TagKey

fn eq(&self, other: &TagKey) -> 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 PartialOrd for TagKey

fn partial_cmp(&self, other: &TagKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for TagKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
