Struct VersionReq 

pub struct VersionReq(/* private fields */);

A version requirement string as it appears in a manifest file.

This is deliberately permissive: it stores whatever bytes the manifest contained (e.g. "^1.0", ">=2.0,<3.0", "*"), including the empty string. No parsing, validation, trimming, or normalization is performed by this type — ecosystems that need to parse a requirement (via semver, node-semver, pep440_rs, etc.) do so from VersionReq::as_str, not from this type. Note that deps-go’s GoDependency.version also uses this type even though it holds an exact pinned version (e.g. "v1.9.1"), not a range or constraint — Go modules don’t have a separate “requirement” concept, so the exact version doubles as the requirement.

Examples

use deps_core::VersionReq;

let req = VersionReq::new("^1.0");
assert_eq!(req.as_str(), "^1.0");
assert_eq!(req, "^1.0");

Implementations

impl VersionReq

pub fn new(value: impl Into<String>) -> Self

Wraps value as a VersionReq, unchanged.

This never fails and never modifies its input: an empty string is a valid VersionReq, as is a string with surrounding whitespace.

Examples

use deps_core::VersionReq;

let req = VersionReq::new(String::from(">=1.0"));
assert_eq!(req.as_str(), ">=1.0");

pub fn as_str(&self) -> &str

Returns the version requirement as a string slice.

Examples

use deps_core::VersionReq;

let req = VersionReq::new("~1.2");
assert_eq!(req.as_str(), "~1.2");

pub fn into_string(self) -> String

Consumes the VersionReq, returning the wrapped String.

Examples

use deps_core::VersionReq;

let req = VersionReq::new("~1.2");
let owned: String = req.into_string();
assert_eq!(owned, "~1.2");

Trait Implementations

impl AsRef<str> for VersionReq

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for VersionReq

fn clone(&self) -> VersionReq

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersionReq

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

Formats the value using the given formatter.

impl Display for VersionReq

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

Formats the value using the given formatter.

impl Eq for VersionReq

impl From<&str> for VersionReq

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for VersionReq

fn from(value: String) -> Self

Converts to this type from the input type.

impl Hash for VersionReq

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 VersionReq

fn eq(&self, other: &VersionReq) -> 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 PartialEq<&str> for VersionReq

fn eq(&self, other: &&str) -> 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 PartialEq<str> for VersionReq

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