Struct PackageName

pub struct PackageName {
    pub namespace: String,
    pub name: String,
    pub version: Option<Version>,
}

A structure used to keep track of the name of a package, containing optional information such as a namespace and version information.

This is directly encoded as an “ID” in the binary component representation with an interfaced tacked on as well.

Fields

namespace: String

A namespace such as wasi in wasi:foo/bar

name: String

The kebab-name of this package, which is always specified.

version: Option<Version>

Optional major/minor version information.

Implementations

impl PackageName

pub fn interface_id(&self, interface: &str) -> String

Returns the ID that this package name would assign the interface name specified.

pub fn version_compat_track(version: &Version) -> Version

Determines the “semver compatible track” for the given version.

This method implements the logic from the component model where semver versions can be compatible with one another. For example versions 1.2.0 and 1.2.1 would be considered both compatible with one another because they’re on the same semver compatible track.

This predicate is used during Resolve::merge_world_imports_based_on_semver for example to determine whether two imports can be merged together. This is additionally used when creating components to match up imports in core wasm to imports in worlds.

pub fn version_compat_track_string(version: &Version) -> String

Returns the string corresponding to PackageName::version_compat_track. This is done to match the component model’s expected naming scheme of imports and exports.

Trait Implementations

impl Clone for PackageName

fn clone(&self) -> PackageName

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PackageName

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

Formats the value using the given formatter.

impl Display for PackageName

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

Formats the value using the given formatter.

impl From<PackageName> for String

fn from(name: PackageName) -> String

Converts to this type from the input type.

impl Hash for PackageName

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 Ord for PackageName

fn cmp(&self, other: &PackageName) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PackageName

fn eq(&self, other: &PackageName) -> 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 PartialOrd for PackageName

fn partial_cmp(&self, other: &PackageName) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PackageName

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for PackageName
