Struct Args

    pub cmd: Option<Command>,
    pub url: String,
    pub dir: Option<String>,
    pub no_path: bool,
    pub name: Vec<String>,
    pub alias: Option<String>,

}

Fields

cmd: Option<Command>

url: String

GitHub repo (owner/repo), release URL, or artifact URL

dir: Option<String>

Installation directory for downloaded binaries

no_path: bool

Skip adding installed binaries to PATH

name: Vec<String>

Filter artifacts by name (comma-separated, word-boundary match)

Matches filenames whose stem starts with the given name followed by a separator (-, _, .) or end-of-string. This prevents e.g. --name qjs from matching qjsc-linux-x86.

alias: Option<String>

Rename the installed binary

target: Option<Target>

Target platform (e.g., x86_64-unknown-linux-gnu)

retry: usize

Number of retry attempts for failed downloads

proxy: Option<Proxy>

GitHub proxy to use (github, ghproxy, etc.)

timeout: Option<u64>

Network request timeout in seconds

strip: Option<bool>

Strip debug symbols from executable

upx: Option<bool>

Compress executable with UPX

quiet: bool

Suppress all output messages

fuzzy: bool

Use fuzzy target matching (match arch+os, ignoring abi)

By default ei requires an exact target triple match (including the abi, e.g. gnu vs musl). Enable this to fall back to a (arch, os) match when no exact match is found, so assets whose filenames omit the abi (e.g. “mihomo-linux-amd64.tar.gz” parsed as gnu) can still be selected when you requested musl.

regex: Option<String>

Regex pattern to match against the original GitHub asset filenames

When supplied, the regex is matched directly against each asset’s original filename (e.g. “mpv-v0.41.0-dev-g4c220ffd9-x86_64-pc-windows-msvc.zip”), bypassing guess_target entirely. This gives you full control over which asset to select when filenames use non-standard naming that confuses automatic target detection.

The regex must match exactly one asset; matching zero or multiple is an error. Examples: –regex “x86_64-pc-windows-msvc” (match a specific triple) –regex “macos-15-arm” (match a macOS variant) –regex “aarch64-pc-windows-msvc\.zip$” (anchor to file extension)

Trait Implementations

impl Args for Args

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl Clone for Args

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CommandFactory for Args

fn command<'b>() -> Command

Build a Command that can instantiate Self.

fn command_for_update<'b>() -> Command

Build a Command that can update self.

impl Debug for Args

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

Formats the value using the given formatter.

impl Default for Args

fn default() -> Self

Returns the “default value” for a type.
