Struct SimplifiedMarkerTree 

pub struct SimplifiedMarkerTree(/* private fields */);

A simplified marker is just like a normal marker, except it has possibly been simplified by requires-python.

A simplified marker should only exist in contexts where a requires-python setting can be assumed. In order to get a “normal” marker out of a simplified marker, one must re-contextualize it by adding the requires-python constraint back to the marker.

Implementations

impl SimplifiedMarkerTree

pub fn new(requires_python: &RequiresPython, marker: MarkerTree) -> Self

Simplifies the given markers by assuming the given requires-python bound is true.

pub fn into_marker(self, requires_python: &RequiresPython) -> MarkerTree

Complexifies the given markers by adding the given requires-python as a constraint to these simplified markers.

pub fn try_to_string(self) -> Option<String>

Attempts to convert this simplified marker to a string.

This only returns None when the underlying marker is always true, i.e., it matches all possible marker environments.

pub fn as_simplified_marker_tree(self) -> MarkerTree

Returns the underlying marker tree without re-complexifying them.

Trait Implementations

impl Clone for SimplifiedMarkerTree

fn clone(&self) -> SimplifiedMarkerTree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SimplifiedMarkerTree

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

Formats the value using the given formatter.

impl Default for SimplifiedMarkerTree

fn default() -> SimplifiedMarkerTree

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SimplifiedMarkerTree

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for SimplifiedMarkerTree

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

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

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