Variants

Any

Req(VersionReq)

Locked(Version, VersionReq)

The exact locked version and the original version requirement.

Implementations

impl OptVersionReq

pub fn exact(version: &Version) -> Self

pub fn is_exact(&self) -> bool

pub fn lock_to(&mut self, version: &Version)

pub fn is_locked(&self) -> bool

pub fn locked_version(&self) -> Option<&Version>

Gets the version to which this req is locked, if any.

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

Trait Implementations

impl Clone for OptVersionReq

fn clone(&self) -> OptVersionReq

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OptVersionReq

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

Formats the value using the given formatter.

impl Display for OptVersionReq

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

Formats the value using the given formatter.

impl From<VersionReq> for OptVersionReq

fn from(req: VersionReq) -> Self

Converts to this type from the input type.

impl Hash for OptVersionReq

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 PartialEq<OptVersionReq> for OptVersionReq

fn eq(&self, other: &OptVersionReq) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
