Struct Bound 

pub struct Bound { /* private fields */ }

Represents a version boundary (inclusive or exclusive). Used to determine the range of versions a constraint covers.

Implementations

impl Bound

pub fn new(version: impl Into<String>, inclusive: bool) -> Self

Create a new bound.

pub fn zero() -> Self

The zero bound: 0.0.0.0-dev (inclusive). Represents the absolute minimum version.

pub fn positive_infinity() -> Self

Positive infinity bound (exclusive). PHP uses PHP_INT_MAX which is 9223372036854775807 on 64-bit.

pub fn version(&self) -> &str

Get the version string.

pub const fn is_inclusive(&self) -> bool

Check if this bound is inclusive.

pub fn is_zero(&self) -> bool

Check if this is the zero bound.

pub fn is_positive_infinity(&self) -> bool

Check if this is the positive infinity bound.

pub fn compare_to(&self, other: &Self) -> Ordering

Compare this bound to another. Returns ordering based on version comparison and inclusivity.

pub fn compare_as_lower(&self, other: &Self) -> Ordering

Compare for lower bound context. In lower bounds, inclusive is “smaller” (starts earlier).

pub fn compare_as_upper(&self, other: &Self) -> Ordering

Compare for upper bound context. In upper bounds, exclusive is “smaller” (ends earlier).

Trait Implementations

impl Clone for Bound

fn clone(&self) -> Bound

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bound

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

Formats the value using the given formatter.

impl Display for Bound

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

Formats the value using the given formatter.

impl PartialEq for Bound

fn eq(&self, other: &Bound) -> 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.
