Enum Clause 

pub enum Clause {
    All(Vec<Requirement>),
    Between(Box<Version>, Box<Version>),
    Only(Requirement),
}

A single clause within a version range.

Variants

All(Vec<Requirement>)

A list of requirements that must all match, for example >=1.2 && <2.

Between(Box<Version>, Box<Version>)

A bounded range between two fully qualified versions, inclusive on both ends, for example 1.2.3 - 2.3.4. The versions are boxed to keep the size of this enum down.

Only(Requirement)

A single requirement.

Implementations

impl Clause

pub fn get_scope(&self) -> Option<&str>

Returns the version scope if available. A clause with multiple requirements only has a scope if all scoped requirements share the same scope, while requirements without a scope are ignored.

pub fn set_scope(&mut self, scope: impl AsRef<str>)

Set the scope on either the current requirement(s) or version(s).

Trait Implementations

impl Clone for Clause

fn clone(&self) -> Clause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Clause

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

Formats the value using the given formatter.

impl Display for Clause

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

Formats the value using the given formatter.

impl Eq for Clause

impl Hash for Clause

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 MatchesVersion for Clause

fn matches(&self, version: &Version) -> bool

Returns true if the provided version satisfies this shape, following the same rules as the [semver] crate.

impl Ord for Clause

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Clause

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