Implementations

impl<'a> UpstreamVersionComponent<'a>

pub fn new(prefix: Option<u64>, suffix: &'a str) -> Self

Construct a new component.

pub fn parse(segment: &'a str) -> Self

Parse a component from segment text.

assert_eq!(UpstreamVersionComponent::parse("").components(), (None, ""));
assert_eq!(
    UpstreamVersionComponent::parse("alpha").components(),
    (None, "alpha"),
);
assert_eq!(
    UpstreamVersionComponent::parse("123").components(),
    (Some(123), ""),
);
assert_eq!(
    UpstreamVersionComponent::parse("123alpha").components(),
    (Some(123), "alpha"),
);
assert_eq!(
    UpstreamVersionComponent::parse("0alpha").components(),
    (Some(0), "alpha"),
);
assert_eq!(
    UpstreamVersionComponent::parse("00alpha").components(),
    (Some(0), "alpha"),
);

pub fn components(&self) -> (Option<u64>, &'a str)

Exact the numeric prefix and non-numeric suffix.

Trait Implementations

impl<'a> Clone for UpstreamVersionComponent<'a>

fn clone(&self) -> UpstreamVersionComponent<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for UpstreamVersionComponent<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for UpstreamVersionComponent<'a>

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<'a> Ord for UpstreamVersionComponent<'a>

fn cmp(&self, other: &UpstreamVersionComponent<'a>) -> 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<'a> PartialEq for UpstreamVersionComponent<'a>

fn eq(&self, other: &UpstreamVersionComponent<'a>) -> 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<'a> PartialOrd for UpstreamVersionComponent<'a>

fn partial_cmp(&self, other: &UpstreamVersionComponent<'a>) -> 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.
