Struct ImageMetadataStore 

pub struct ImageMetadataStore { /* private fields */ }

Optional, policy-owned image metadata used by ecosystem components.

This is intentionally not a UiServices capability:

• the mechanism layer (fret-ui) must remain backend-agnostic, and
• ADR 0124 explicitly discourages implicit layout dependence on intrinsic image size.

Instead, apps/components that already know image dimensions (e.g. decoders, caches, streaming sources) can record them here to enable ergonomic recipes like “aspect-ratio wrappers”.

Implementations

impl ImageMetadataStore

pub fn set_intrinsic_size_px(&mut self, image: ImageId, size_px: (u32, u32))

pub fn clear_intrinsic_size_px(&mut self, image: ImageId)

pub fn intrinsic_size_px(&self, image: ImageId) -> Option<(u32, u32)>

pub fn aspect_ratio(&self, image: ImageId) -> Option<f32>
