Struct Version 

pub struct Version {
    pub major: u32,
    pub minor: u32,
}

The version of a @link specification, in the form of a major and minor version numbers.

Fields

major: u32

The major number part of the version.

minor: u32

The minor number part of the version.

Implementations

impl Version

pub fn satisfies(&self, required: &Version) -> bool

Whether this version satisfies the provided required version.

assert!(&Version { major: 1, minor: 0 }.satisfies(&Version{ major: 1, minor: 0 }));
assert!(&Version { major: 1, minor: 2 }.satisfies(&Version{ major: 1, minor: 0 }));

assert!(!(&Version { major: 2, minor: 0 }.satisfies(&Version{ major: 1, minor: 9 })));
assert!(!(&Version { major: 0, minor: 9 }.satisfies(&Version{ major: 0, minor: 8 })));

pub fn satisfies_range(&self, min: &Version, max: &Version) -> bool

Verifies whether this version satisfies the provided version range.

Panics

The min and max must be the same major version, and max minor version must be higher than min’s. Else, you get a panic.

Examples

assert!(&Version { major: 1, minor: 1 }.satisfies_range(&Version{ major: 1, minor: 0 }, &Version{ major: 1, minor: 10 }));

assert!(!&Version { major: 2, minor: 0 }.satisfies_range(&Version{ major: 1, minor: 0 }, &Version{ major: 1, minor: 10 }));

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl Display for Version

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

Display a specification version number.

assert_eq!(Version { major: 2, minor: 3 }.to_string(), "2.3")

impl FromStr for Version

type Err = SpecError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Ord for Version

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

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

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