Struct VersionConstraint 

pub struct VersionConstraint {
    pub spec: ConstraintSpec,
    pub native_syntax: Option<String>,
}

Wrapper carrying both the typed ConstraintSpec and the original native syntax — handy for diagnostics + round-tripping back to the source manifest.

Fields

spec: ConstraintSpec

native_syntax: Option<String>

Original adapter-native syntax (e.g. ~> 1.2.3 for Bundler). Optional — adapters that lose the original syntax during parsing leave this None.

Implementations

impl VersionConstraint

pub const fn from_spec(spec: ConstraintSpec) -> Self

Convenience: build from a typed spec without retaining the native syntax. Useful in tests + adapter-independent code.

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

Does this constraint accept the supplied version? Pure function over the typed spec — adapter is never consulted.

Trait Implementations

impl Clone for VersionConstraint

fn clone(&self) -> VersionConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersionConstraint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VersionConstraint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for VersionConstraint

impl PartialEq for VersionConstraint

fn eq(&self, other: &VersionConstraint) -> 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 Serialize for VersionConstraint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
