Enum cargo::util::OptVersionReq

pub enum OptVersionReq {
    Any,
    Req(VersionReq),
    Locked(Version, VersionReq),
    Precise(Version, VersionReq),
}

Variants

Any

Req(VersionReq)

Locked(Version, VersionReq)

The exact locked version and the original version requirement.

Precise(Version, VersionReq)

The exact requested version and the original version requirement.

This looks identical to OptVersionReq::Locked but has a different meaning, and is used for the --precise field of cargo update. See comments in OptVersionReq::matches for more.

Implementations

impl OptVersionReq

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

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

pub fn is_exact(&self) -> bool

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

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

Makes the requirement precise to the requested version.

This is used for the --precise field of cargo update.

pub fn is_precise(&self) -> bool

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

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

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_prerelease(&self, version: &Version) -> bool

Since Semver does not support prerelease versions, the simplest implementation is taken here without comparing the prerelease section. The logic here is temporary, we’ll have to consider more boundary conditions later, and we’re not sure if this part of the functionality should be implemented in semver or cargo.

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 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.

impl Eq for OptVersionReq

impl StructuralPartialEq for OptVersionReq

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
