Enum pep440_rs::LocalSegment

pub enum LocalSegment {
    String(String),
    Number(u64),
}

A part of the local version identifier

Local versions are a mess:

Comparison and ordering of local versions considers each segment of the local version (divided by a .) separately. If a segment consists entirely of ASCII digits then that section should be considered an integer for comparison purposes and if a segment contains any ASCII letters then that segment is compared lexicographically with case insensitivity. When comparing a numeric and lexicographic segment, the numeric section always compares as greater than the lexicographic segment. Additionally a local version with a great number of segments will always compare as greater than a local version with fewer segments, as long as the shorter local version’s segments match the beginning of the longer local version’s segments exactly.

Luckily the default Ord implementation for Vec<LocalSegment> matches the PEP 440 rules.

Variants

String(String)

Not-parseable as integer segment of local version

Number(u64)

Inferred integer segment of local version

Trait Implementations

impl Clone for LocalSegment

fn clone(&self) -> LocalSegment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LocalSegment

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

Formats the value using the given formatter.

impl Display for LocalSegment

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

Formats the value using the given formatter.

impl Hash for LocalSegment

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 LocalSegment

fn cmp(&self, other: &Self) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for LocalSegment

fn eq(&self, other: &LocalSegment) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for LocalSegment

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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