StyleResolutionView

Struct StyleResolutionView 

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

A concrete IncrementalView that resolves styles by merging a base (theme) style with per-widget overrides.

When the theme changes, only widgets whose resolved style actually differs are emitted as output deltas.

§Materialized View

Maps StyleKey (widget ID) → ResolvedStyleValue (hash of resolved style). The resolved style is base_hash XOR override_hash — a simplified model of the real merge(child, parent) operation.

Implementations§

Source§

impl StyleResolutionView

Source

pub fn new(label: impl Into<String>, base_hash: u64) -> Self

Create a new style resolution view with the given base theme hash.

Source

pub fn set_base(&mut self, base_hash: u64)

Set the base theme hash. All resolved styles will be recomputed.

Source

pub fn base_hash(&self) -> u64

Get the current base hash.
