Struct Instantiable 

pub struct Instantiable {
    pub capability: &'static str,
    pub binding_prefix: &'static str,
    pub options: &'static [(&'static str, OptionKind)],
    pub required: &'static [&'static str],
    pub bare: bool,
}

A capability a context may declare instances of (S4a, #1966, track D3).

Fields

capability: &'static str

The capability’s name in its unit (Kv).

binding_prefix: &'static str

The prefix of each instance’s Worker binding name: KV makes capability Sessions = Kv bind as KV_SESSIONS.

options: &'static [(&'static str, OptionKind)]

The creation options (@name(…)) an instance may carry, each with the one literal its value is (standard-library P3, #2342: @worker("…") takes a string, @limit(100) an Int, @period(60.seconds) a Duration); any other is refused. Empty when the kind takes none yet.

required: &'static [&'static str]

The options every instance must carry (interop I5, #1972): a Service names the Worker it reaches, so it has no default. A subset of Instantiable::options.

bare: bool

Whether the base capability is usable bare, through given Kv, as well as through instances. false for a kind whose every use needs an option: a bare Service would name no Worker.

Implementations

impl Instantiable

pub fn option_kind(&self, name: &str) -> Option<OptionKind>

The kind of literal option name takes, or None when it is not one of this kind’s options.

pub fn option_names(&self) -> impl Iterator<Item = &'static str> + '_

The names of this kind’s options, in declaration order.

Trait Implementations

impl Clone for Instantiable

fn clone(&self) -> Instantiable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Instantiable

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

Formats the value using the given formatter.

impl PartialEq for Instantiable

fn eq(&self, other: &Instantiable) -> 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.
