Enum BuiltinServer 

#[non_exhaustive]
pub enum BuiltinServer {
    RustAnalyzer,
    Pyright,
    TypescriptLanguageServer,
    Gopls,
    Clangd,
    Zls,
}

Language servers mcpls ships a default configuration for.

Single source of truth for each builtin’s executable name (Self::as_str) and its install hint, so spawn-failure guidance cannot drift from the defaults.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RustAnalyzer

rust-analyzer for Rust.

Pyright

pyright for Python.

TypescriptLanguageServer

typescript-language-server for TypeScript.

Gopls

gopls for Go.

Clangd

clangd for C and C++.

Zls

zls for Zig.

Implementations

impl BuiltinServer

pub const ALL: [Self; 6]

Every variant, in declaration order.

pub const fn as_str(self) -> &'static str

The spelling as written on the wire or a command line.

impl BuiltinServer

pub const fn workspace_code(self) -> &'static str

The workspace-supplied code this server can run, for the message that explains why untrusted mode refused it.

pub const fn install_hint(self) -> &'static str

One-line instruction for installing this server.

pub const fn early_exit_hint(self) -> Option<&'static str>

Likely cause of this server exiting before completing the initialize handshake, if one is known.

Only rust-analyzer has one: rustup installs a rust-analyzer proxy even when the component is not installed, and the proxy exits at once.

pub const fn is_npm_package(self) -> bool

Whether this server is distributed through npm, and so is installed as a .cmd shim on Windows.

pub fn matches_command(self, command: &str) -> bool

Whether command launches this builtin: its file stem is this server’s executable name, so an absolute path or a Windows .cmd shim matches. Case-insensitive on Windows.

Examples

use mcpls_core::config::BuiltinServer;

let tsls = BuiltinServer::TypescriptLanguageServer;
assert!(tsls.matches_command("typescript-language-server"));
assert!(tsls.matches_command("/usr/local/bin/typescript-language-server"));
assert!(tsls.matches_command("typescript-language-server.cmd"));
assert!(!tsls.matches_command("tsc"));

pub fn from_command(command: &str) -> Option<Self>

Look up a builtin by its exact executable name.

Examples

use mcpls_core::config::BuiltinServer;

assert_eq!(BuiltinServer::from_command("gopls"), Some(BuiltinServer::Gopls));
assert_eq!(BuiltinServer::from_command("/usr/bin/gopls"), None);
