Enum Capability 

pub enum Capability {
    Read,
    Write,
    Http,
    Events,
    Session,
    Ui,
    Exec,
    Env,
    Tool,
    Log,
}

Enumeration of all recognised extension capabilities.

Each variant maps 1-to-1 with a string token used in policy configuration (e.g. "read", "exec"). The canonical string is the #[serde(rename_all = "snake_case")] form.

Variants

Read

Read files and directories.

Write

Write / create / delete files and directories.

Http

Outbound HTTP requests.

Events

Subscribe to and emit lifecycle events.

Session

Access session state (messages, model, labels, etc.).

Ui

UI operations (status, widgets, notifications).

Exec

Execute shell commands (dangerous).

Env

Read environment variables (dangerous — may leak secrets).

Tool

Generic tool invocation.

Log

Logging (always allowed, included for completeness).

Implementations

impl Capability

pub fn parse(s: &str) -> Option<Self>

Parse a string token into a Capability, case-insensitive. Returns None for unrecognised tokens.

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

Canonical string token (matches serde rename).

pub const fn is_dangerous(self) -> bool

Whether this capability is classified as dangerous.

Dangerous capabilities default to Deny in Strict/Prompt modes and require explicit opt-in or user confirmation.

pub const fn dangerous_list() -> &'static [Self]

List of all dangerous capabilities.

pub const fn index(self) -> usize

Ordinal index for array-based snapshot lookups.

Trait Implementations

impl Clone for Capability

fn clone(&self) -> Capability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Capability

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Capability

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Capability

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

Formats the value using the given formatter.

impl Hash for Capability

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Capability

fn eq(&self, other: &Capability) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Capability

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Capability

impl Eq for Capability

impl StructuralPartialEq for Capability
