Struct EventView 

pub struct EventView {
    pub kind: Option<EventKindView>,
    pub title: String,
    pub detail: String,
    pub severity: i32,
}

Something that happened while nobody was looking: a plugin dropped, a broker session ended (#150).

Every other view answers a question a front end asked. This is the other direction, so it arrives on a stream rather than as a reply.

Why the text is in the payload

title and detail are filled in by the engine rather than derived from the kind by whoever renders it. There are two renderers — the OS notification and the in-app alerts list — and text derived twice is text that drifts. The kind is left for what a renderer needs structurally: the status bar needs to know a feed is down, not how to phrase it.

Fields

kind: Option<EventKindView>

title: String

detail: String

severity: i32

Implementations

impl EventView

pub fn severity(&self) -> SeverityView

Returns the enum value of severity, or the default if the field is set to an invalid enum value.

pub fn set_severity(&mut self, value: SeverityView)

Sets severity to the provided enum value.

impl EventView

pub fn new( kind: EventKindView, title: String, detail: String, severity: SeverityView, ) -> Self

An event, with the kind and the text a renderer shows.

pub fn of(&self) -> Option<&Of>

What happened, structurally, if the sender said.
