Trait MeasurementRead

}

Read-only measurement access used by reconstruction algorithms.

Implementations retain responsibility for storage, caching, preprocessing, and mutation. The opaque frame view may borrow directly from the implementation or own a shared cache handle.

Required Methods

fn frame_count(&self) -> usize

Returns the number of acquisition frames.

fn image_shape(&self) -> (usize, usize)

Returns low-resolution image shape as (height, width).

fn frame_len(&self) -> usize

Returns height * width, the row-major element count of one frame.

fn frame(&self, index: usize) -> Result<impl Deref<Target = [f64]> + '_>

Borrows or shares a row-major intensity frame by zero-based acquisition index.

fn frame_weight(&self, index: usize) -> Result<f64>

Returns a frame’s non-negative reconstruction weight.

fn frame_mask(&self, index: usize) -> Result<Option<&[u8]>>

Borrows an optional row-major binary validity mask for one frame.

fn frame_metadata(&self) -> &[FrameMetadata]

Borrows metadata in acquisition-frame order.

fn validate(&self) -> Result<()>

Checks shapes, counts, finite intensities, metadata, weights, and masks.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
