Struct UniversalMarker 

pub struct UniversalMarker { /* private fields */ }

A representation of a marker for use in universal resolution.

(This degrades gracefully to a standard PEP 508 marker in the case of non-universal resolution.)

This universal marker is meant to combine both a PEP 508 marker and a marker for conflicting extras/groups. The latter specifically expresses whether a particular edge in a dependency graph should be followed depending on the activated extras and groups.

A universal marker evaluates to true only when both its PEP 508 marker and its conflict marker evaluate to true.

Implementations

impl UniversalMarker

pub fn combined(self) -> MarkerTree

Returns the internal marker that combines both the PEP 508 and conflict marker.

Trait Implementations

impl Clone for UniversalMarker

fn clone(&self) -> UniversalMarker

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UniversalMarker

impl Debug for UniversalMarker

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

Formats the value using the given formatter.

impl Default for UniversalMarker

fn default() -> UniversalMarker

Returns the “default value” for a type.

impl Eq for UniversalMarker

impl Hash for UniversalMarker

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 UniversalMarker

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

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

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