Struct Attachment 

pub struct Attachment { /* private fields */ }

One file with stable identity, presentation metadata, and upload state.

Equality compares every field; thumbnails compare by identity so a snapshot that re-attaches the same image does not invalidate rows.

Implementations

impl Attachment

pub fn new(id: impl Into<SharedString>, name: impl Into<SharedString>) -> Self

Creates a ready attachment; the kind is inferred from the name.

pub fn kind(self, kind: AttachmentKind) -> Self

Overrides the inferred kind.

pub fn size_bytes(self, size_bytes: u64) -> Self

Sets the size shown in the metadata line.

pub fn detail(self, detail: impl Into<SharedString>) -> Self

Adds a short detail such as 12 pages or 1280×720.

pub fn thumbnail(self, image: Arc<Image>) -> Self

Shows an image thumbnail instead of the kind glyph.

pub fn state(self, state: ProgressState) -> Self

Sets the upload lifecycle: pending or running files are not yet usable, failed ones carry a reason.

pub fn progress(self, fraction: f32) -> Self

Sets the upload fraction (0.0..=1.0) shown while running.

pub fn id(&self) -> &SharedString

Returns the stable attachment identifier.

pub fn name(&self) -> &SharedString

Returns the visible file name.

pub fn attachment_kind(&self) -> AttachmentKind

Returns the kind used for the glyph and label.

pub fn size(&self) -> Option<u64>

Returns the size, if known.

pub fn detail_text(&self) -> Option<&SharedString>

Returns the optional detail text.

pub fn thumbnail_image(&self) -> Option<&Arc<Image>>

Returns the thumbnail, if any.

pub fn upload_state(&self) -> &ProgressState

Returns the upload lifecycle.

pub fn is_ready(&self) -> bool

Returns whether the file is usable (uploaded, not failed).

pub fn summary(&self) -> String

The one-line metadata shown under the name and read to assistive technology: kind, size, detail, or the lifecycle when not ready.

pub fn accessibility_label(&self) -> String

The accessible name: file name plus summary.
