Struct ImageDecodeCache

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

Caches the results of decoding re_types::archetypes::EncodedImage.

Implementations§

Source§

impl ImageDecodeCache

Source

pub fn entry( &mut self, blob_row_id: RowId, image_bytes: &[u8], media_type: Option<&MediaType>, ) -> Result<ImageInfo, ImageLoadError>

Decode some image data and cache the result.

The row_id should be the RowId of the blob. NOTE: images are never batched atm (they are mono-archetypes), so we don’t need the instance id here.
