Struct Resolver 

pub struct Resolver { /* private fields */ }

An opt-in evaluator that reuses unchanged View evaluation across frames.

Resolver has the same observable result as resolve. It retains only core reconciliation inputs and materialized output; the current View and available area still decide layout. Application state, clocks, redraw scheduling, terminal capabilities, and graphics protocol state stay with the host that composes those independent capabilities.

The free resolve function remains the ordinary stateless path and does not construct this cache metadata.

Implementations

impl Resolver

pub const fn new() -> Self

Creates an empty retained evaluator.

pub fn resolve( &mut self, view: &View, available: Available, ) -> Result<ResolvedView, LayoutError>

Resolves one immutable View snapshot, reusing unchanged subtree output.

A changed Viewport origin reprojects its retained child. Changes to content or to a settled layout input invalidate the affected artifact, while independent unchanged subtrees remain reusable.

pub fn clear(&mut self)

Drops every retained evaluation artifact.

Trait Implementations

impl Default for Resolver

fn default() -> Self

Returns the “default value” for a type.
