Struct wasmer_pack::PackageName

pub struct PackageName { /* private fields */ }

The name of a package from WAPM (e.g. wasmer/wasmer-pack).

Syntax:

• A PackageName consists of a “name” and an optional “namespace or username”
• The “namespace or username” may be an “identifier” or the “_” namespace (used for backwards compatibility)
• If a “namespace or username” isn’t provided, it is assumed to be a package alias and will be resolved to a package by the WAPM backend
• “Identifiers” can only contain alphanumeric ascii characters, _, and -
• “Identifiers” must also start with an ascii character and be at most 100 characters long

Implementations

impl PackageName

pub fn parse(raw: &str) -> Result<Self, Error>

pub fn name(&self) -> &str

pub fn set_name(&mut self, name: impl Into<String>)

pub fn namespace(&self) -> &Namespace

pub fn javascript_package(&self) -> String

Get the NPM equivalent of this PackageName.

This should satisfy NPM’s naming rules:

• package name length should be greater than zero
• all the characters in the package name must be lowercase i.e., no uppercase or mixed case names are allowed
• package name can consist of hyphens
• package name must not contain any non-url-safe characters (since name ends up being part of a URL)
• package name should not start with . or _
• package name should not contain any spaces
• package name should not contain any of the following characters: ~)(’!*
• package name cannot be the same as a node.js/io.js core module nor a reserved/blacklisted name. For example, the following names are invalid:
  • http
  • stream
  • node_modules
  • favicon.ico
• package name length cannot exceed 214

pub fn python_name(&self) -> String

Get the PyPI equivalent of this PackageName.

This should satisfy the naming scheme outlined in PEP 8:

Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.

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 FromStr for PackageName

type Err = Error

The associated error which can be returned from parsing.

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

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

impl PartialEq<PackageName> for PackageName

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