Enum NoEffect 

pub enum NoEffect {}

The vocabulary of a surface that has no effects.

Trait Implementations

impl Clone for NoEffect

fn clone(&self) -> NoEffect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoEffect

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

Formats the value using the given formatter.

impl Effect for NoEffect

const OPERATION: &'static str = "tilo.no-effect"

The operation type every effect of the vocabulary travels under: unique per vocabulary, like a resource’s kind.

fn declarations() -> Vec<EffectDecl>

One declaration per effect, in order.

fn id(&self) -> &'static str

This effect’s id among the declarations.

fn arguments(&self) -> Map<String, Value>

This effect’s arguments, named as its declaration’s parameters.

fn decode(id: &str, _: &Map<String, Value>) -> Result<NoEffect, String>

The effect id with arguments, as a caller invoked it.

fn declaration(id: &str) -> Option<EffectDecl>

The declaration of the effect id, built alone: what binding one effect to an item reads, so offering it on many items costs one declaration each, not the whole vocabulary.

fn specs() -> Vec<ActionSpec>

The published action of every effect offered on the resource: all but the row ones, which are offered only bound.

fn bound(&self) -> ActionSpec

This effect with its arguments as one action that takes none: what a published child or a live row offers (open this snippet, stop this process), answered by the vocabulary’s handler like any other invocation of the effect, under the same contract as its declaration.

fn bound_asking(&self, asking: &[&str]) -> ActionSpec

This effect bound to the item it acts on, as bound, still asking its caller for the arguments named in asking: rename this file, to a name the caller gives. The bound arguments are this effect’s own; an asked one the caller supplies replaces it.

fn bound_asking_params(&self, params: Vec<ActionParam>) -> ActionSpec

bound_asking with the asked parameters given whole, narrowed for this item: the applications that can open this file as the choices of app.

fn item_specs(field: &str, item: &Id) -> Vec<ActionSpec>

The effects offered on the item item of the collection field (#[effect(item = field)]), each with its first parameter bound to the item and the rest still asked.

fn from_payload(payload: &[u8]) -> Result<Self, String>

Decode one invocation’s payload, as the operation’s specs encode it.
