Struct VariantSpec 

pub struct VariantSpec { /* private fields */ }

Canonical runtime representation of a problem variant.

Unlike raw BTreeMap<String, String>, construction from pairs rejects duplicate dimensions.

Implementations

impl VariantSpec

pub fn try_from_pairs<I, K, V>(pairs: I) -> Result<Self, ConstructionError>

where I: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<String>,

Create a VariantSpec from key-value pairs, rejecting duplicate dimensions.

Returns an error if the same dimension key appears more than once.

pub fn try_from_map( map: BTreeMap<String, String>, ) -> Result<Self, ConstructionError>

Create a VariantSpec from an existing BTreeMap.

pub fn as_map(&self) -> &BTreeMap<String, String>

View the dimensions as a map.

pub fn into_map(self) -> BTreeMap<String, String>

Consume this VariantSpec and return the underlying map.

pub fn update_dimension( &mut self, key: impl Into<String>, value: impl Into<String>, )

Update or add a single dimension.

Trait Implementations

impl Clone for VariantSpec

fn clone(&self) -> VariantSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariantSpec

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

Formats the value using the given formatter.

impl Eq for VariantSpec

impl Hash for VariantSpec

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

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 VariantSpec

fn cmp(&self, other: &VariantSpec) -> 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 VariantSpec

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

fn partial_cmp(&self, other: &VariantSpec) -> 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.
