Variants

MatchNone

Implementations

impl Constraint

pub fn new(op: Op, version: impl Into<String>) -> Constraint

pub fn is_single(&self) -> bool

pub fn match_specific( &self, provider: &Constraint, compare_branches: bool, ) -> bool

Constraint::matchSpecific($provider, $compareBranches): self is the constraint, provider the candidate version (or another simple constraint).

pub fn matches(&self, provider: &Constraint) -> bool

ConstraintInterface::matches($provider).

pub fn matches_version(&self, version: &str) -> bool

CompilingMatcher::match($constraint, OP_EQ, $version), the form Composer uses everywhere to test a version.

pub fn create(constraints: Vec<Constraint>, conjunctive: bool) -> Constraint

MultiConstraint::create($constraints, $conjunctive).

pub fn lower_bound(&self) -> Bound

pub fn upper_bound(&self) -> Bound

impl Eq for Constraint

impl Hash for Constraint

fn hash<__H: Hasher>(&self, state: &mut __H)
