The Zed Rust Extension API
This crate lets you write extensions for Zed in Rust.
Extension Manifest
You'll need an extension.toml
file at the root of your extension directory, with the following structure:
id = "my-extension"
name = "My Extension"
description = "..."
version = "0.0.1"
schema_version = 1
authors = ["Your Name <you@example.com>"]
repository = "https://github.com/your/extension-repository"
Cargo metadata
Zed extensions are packaged as WebAssembly files. In your Cargo.toml, you'll
need to set your crate-type
accordingly:
[dependencies]
zed_extension_api = "0.1.0"
[lib]
crate-type = ["cdylib"]
Implementing an Extension
To define your extension, create a type that implements the Extension
trait, and register it.
use zed_extension_api as zed;
struct MyExtension {
// ... state
}
impl zed::Extension for MyExtension {
// ...
}
zed::register_extension!(MyExtension);
Testing your extension
To run your extension in Zed as you're developing it:
- Open the extensions view using the
zed: extensions
action in the command palette. - Click the
Install Dev Extension
button in the top right - Choose the path to your extension directory.
