Struct Package

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

version: Option<String>

Implementations

impl Package

pub fn already_installed(&self, wasmer_dir: &Path) -> Option<PathBuf>

Checks whether the package is already installed, if yes, returns the path to the root dir

pub fn is_url_already_installed(url: &Url, wasmer_dir: &Path) -> Option<PathBuf>

Checks if the URL is already installed, note that {url}@{version} and {url} are treated the same

pub fn hash_url(url: &str) -> String

Returns the hash of the URL with a maximum of 128 bytes length (necessary for not erroring on filesystem limitations)

pub fn unhash_url(hashed: &str) -> String

Returns the hash of the URL with a maximum of 64 bytes length

pub fn get_hash(&self, registry: &str) -> String

Returns the hash of the package URL without the version (because the version is encoded as @version and isn’t part of the hash itself)

pub fn file(&self) -> String

Returns the filename for this package

pub fn package(&self) -> String

Returns the {namespace}/{name} package name

pub fn url(&self, registry: &str) -> Result<Url, Error>

Returns the full URL including the version for this package

pub fn get_path(&self, wasmer_dir: &Path) -> Result<PathBuf, Error>

Returns the path to the installation directory. Does not check whether the installation directory already exists.

Trait Implementations

impl Clone for Package

fn clone(&self) -> Package

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Package

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

Formats the value using the given formatter.

impl Default for Package

fn default() -> Package

Returns the “default value” for a type.

impl Display for Package

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

Formats the value using the given formatter.

impl FromStr for Package

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 Ord for Package

fn cmp(&self, other: &Package) -> 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 Package

fn eq(&self, other: &Package) -> 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 Package

fn partial_cmp(&self, other: &Package) -> 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.
