Struct TargetScope 

#[non_exhaustive]
pub struct TargetScope {
    pub entity: Option<String>,
    pub view_id: Option<String>,
    pub view_kind: Option<ViewKind>,
    pub nesting: Nesting,
}

Which views an action or a controller is for. Anything left out does not narrow it.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

entity: Option<String>

Only views of this entity.

view_id: Option<String>

Only the view with this id.

view_kind: Option<ViewKind>

Only views of this kind.

nesting: Nesting

Root or nested.

Implementations

impl TargetScope

pub fn any() -> Self

Every view.

pub fn entity(self, entity: impl Into<String>) -> Self

Only views of this entity.

pub fn view_id(self, id: impl Into<String>) -> Self

Only the view with this id.

pub fn view_kind(self, kind: ViewKind) -> Self

Only views of this kind.

pub fn nesting(self, nesting: Nesting) -> Self

Root or nested.

pub fn covers(&self, view: Option<&ViewInfo>, context: FrameContext) -> bool

Whether it covers this view, in a frame of this context. No view is covered only by what asks nothing of one.
