ViewDivergence

tix::views::divergence

Struct ViewDivergence 

Source 
pub struct ViewDivergence { /* private fields */ }
Expand description

The read-only comparison of live state to a saved plan (data-model §5).

differences is ordered by the field walk in [fields], so two runs over the same inputs report the same list in the same order. in_sync is a convenience summary: it is true exactly when there are no differences and no diagnostics.

Implementations§

Source§

impl ViewDivergence

Source

pub fn between(saved: &ViewPlan, live: &ViewPlan) -> Self

Compare two plans directly, with no marker identity.

Source

pub fn for_marker( marker: &ActiveViewMarker, saved: &ViewPlan, live: &ViewPlan, ) -> Self

Compare live state to a saved plan, keeping the marker’s identity.

Source

pub fn missing_marker(live: &ViewPlan) -> Self

No active view is selected: an explicit diagnostic, never a silent match.

Source

pub fn deleted(view_id: &ViewId, live: &ViewPlan) -> Self

The marker’s view is no longer in the registry (it was deleted).

Source

pub fn unreadable( view_id: &ViewId, live: &ViewPlan, diagnostics: Vec<ViewDiagnostic>, ) -> Self

The saved definition’s plan could not be interpreted, so no comparison was possible. The refusal’s own diagnostics are carried through verbatim.

Source

pub fn view_id(&self) -> Option<&ViewId>

The saved view the comparison is about, when a marker identified one.

Source

pub fn saved_plan(&self) -> Option<&ViewPlan>

The saved definition’s normalized plan, when it could be read.

Source

pub fn live_plan(&self) -> &ViewPlan

The live normalized plan that was compared.

Source

pub fn differences(&self) -> &[ViewDifference]

The divergent fields, in a fixed field order.

Source

pub fn diagnostics(&self) -> &[ViewDiagnostic]

Problems that prevented or qualified the comparison.

Source

pub fn in_sync(&self) -> bool

Whether the live plan matches the saved plan, with no diagnostics.

False for a missing marker or a deleted view: “nothing to compare” is not “in sync”.
