Struct wasmer_cli::config::env::WasmerEnv

pub struct WasmerEnv {
    wasmer_dir: PathBuf,
    pub(crate) cache_dir: PathBuf,
    pub(crate) registry: Option<UserRegistry>,
    token: Option<String>,
}

Command-line flags for determining the local “Wasmer Environment”.

This is where you access $WASMER_DIR, the $WASMER_DIR/wasmer.toml config file, and specify the current registry.

Fields

wasmer_dir: PathBuf

Set Wasmer’s home directory

cache_dir: PathBuf

The directory cached artefacts are saved to.

registry: Option<UserRegistry>

The registry to fetch packages from (inferred from the environment by default)

token: Option<String>

The API token to use when communicating with the registry (inferred from the environment by default)

Implementations

impl WasmerEnv

pub fn new( wasmer_dir: PathBuf, cache_dir: PathBuf, token: Option<String>, registry: Option<UserRegistry>, ) -> Self

pub fn registry_public_url(&self) -> Result<Url, Error>

Get the “public” url of the current registry (e.g. “https://wasmer.io” instead of “https://registry.wasmer.io/graphql”).

pub fn registry_endpoint(&self) -> Result<Url, Error>

Get the GraphQL endpoint used to query the registry.

pub fn config(&self) -> Result<WasmerConfig, Error>

Load the current Wasmer config.

pub fn proxy(&self) -> Result<Option<Proxy>, Error>

Returns the proxy specified in wasmer config if present

pub fn dir(&self) -> &Path

The directory all Wasmer artifacts are stored in.

pub fn cache_dir(&self) -> &Path

The directory all cached artifacts should be saved to.

pub fn get_token_opt(&self) -> Option<&str>

Retrieve the specified token.

NOTE: In contrast to Self::token, this will not fall back to loading the token from the confg file.

pub fn token(&self) -> Option<String>

The API token for the active registry.

pub fn client_unauthennticated(&self) -> Result<WasmerClient, Error>

pub fn client(&self) -> Result<WasmerClient, Error>

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

impl Parser for WasmerEnv

fn parse() -> Self

Parse from std::env::args_os(), exit on error

fn try_parse() -> Result<Self, Error>

Parse from std::env::args_os(), return Err on error.

fn parse_from<I, T>(itr: I) -> Self

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,

Parse from iterator, exit on error

fn try_parse_from<I, T>(itr: I) -> Result<Self, Error>

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,

Parse from iterator, return Err on error.

fn update_from<I, T>(&mut self, itr: I)

impl PartialEq for WasmerEnv

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