Struct PackageReq 

pub struct PackageReq { /* private fields */ }

A lua package requirement with a name and an optional version requirement.

Implementations

impl PackageReq

pub fn new( name: String, version: Option<String>, ) -> Result<Self, PackageVersionReqError>

pub unsafe fn new_unchecked(name: String, version: Option<String>) -> Self

Safety

Call this only if you are absolutely sure that a PackageReq can be parsed from the arguments. Calling this with invalid arguments is undefined behaviour.

pub fn parse(pkg_constraints: &str) -> Result<Self, PackageReqParseError>

pub fn name(&self) -> &PackageName

pub fn version_req(&self) -> &PackageVersionReq

pub fn matches(&self, package: &PackageSpec) -> bool

Evaluate whether the given package satisfies the package requirement given by self.

Trait Implementations

impl Clone for PackageReq

fn clone(&self) -> PackageReq

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackageReq

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PackageReq

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PackageReq

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

Formats the value using the given formatter.

impl From<PackageName> for PackageReq

fn from(name: PackageName) -> Self

Converts to this type from the input type.

impl From<PackageReq> for LuaDependencySpec

fn from(package_req: PackageReq) -> Self

Converts to this type from the input type.

impl From<PackageSpec> for PackageReq

fn from(value: PackageSpec) -> Self

Converts to this type from the input type.

impl FromLua for PackageReq

fn from_lua(value: Value, lua: &Lua) -> Result<Self>

Performs the conversion.

impl FromStr for PackageReq

type Err = PackageReqParseError

The associated error which can be returned from parsing.

fn from_str(str: &str) -> Result<Self, PackageReqParseError>

Parses a string s to return a value of this type.

impl Hash for PackageReq

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 PackageReq

fn eq(&self, other: &PackageReq) -> 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 TryFrom<PackageReq> for PackageSpec

type Error = PackageSpecFromPackageReqError

The type returned in the event of a conversion error.

fn try_from(value: PackageReq) -> Result<Self, Self::Error>

Performs the conversion.

impl UserData for PackageReq

fn add_methods<M: UserDataMethods<Self>>(methods: &mut M)

Adds custom methods and operators specific to this userdata.

fn add_fields<F>(fields: &mut F)

where F: UserDataFields<Self>,

Adds custom fields specific to this userdata.

fn register(registry: &mut UserDataRegistry<Self>)

Registers this type for use in Lua.

impl Eq for PackageReq
