Struct ExtensionDescriptionStateDTO 

pub struct ExtensionDescriptionStateDTO {

    pub Identifier: Value,
    pub Name: String,
    pub Version: String,
    pub Publisher: String,
    pub Engines: Value,
    pub Main: Option<String>,
    pub Browser: Option<String>,
    pub ModuleType: Option<String>,
    pub IsBuiltin: bool,
    pub IsUnderDevelopment: bool,
    pub ExtensionLocation: Value,
    pub ActivationEvents: Option<Vec<String>>,
    pub Contributes: Option<Value>,
}

Represents the deserialized content of an extension’s package.json file, augmented with location information and other metadata.

This is stored in ApplicationState to provide the extension host with the list of available extensions and their capabilities. VS Code extensions use camelCase in package.json. Serde renames from PascalCase Rust fields to camelCase JSON automatically. Fields that don’t exist in package.json (Identifier, ExtensionLocation, IsBuiltin) default to their zero values on deserialization.

Fields

Identifier: Value

Extension identifier: { value: string, uuid?: string } Not present in package.json — constructed from publisher.name after parsing.

Name: String

Extension name (from package.json “name”)

Version: String

Semantic version string (e.g., “1.0.0”)

Publisher: String

Publisher name or identifier

Engines: Value

Engine compatibility requirements: { vscode: string }

Main: Option<String>

Main entry point path (Node.js runtime)

Browser: Option<String>

Browser entry point path (web extension)

ModuleType: Option<String>

Module type: commonjs or esm

IsBuiltin: bool

Whether this is a built-in extension (not in package.json, set by scanner)

IsUnderDevelopment: bool

Whether extension is under active development

ExtensionLocation: Value

Installation location URI (set by scanner, not in package.json)

ActivationEvents: Option<Vec<String>>

Activation event triggers (e.g., “onStartupFinished”)

Contributes: Option<Value>

Extension contributions (commands, views, etc.)
