Struct ImageInfo 

#[non_exhaustive]
pub struct ImageInfo {
    pub height: Option<UInt>,
    pub width: Option<UInt>,
    pub mimetype: Option<String>,
    pub size: Option<UInt>,
    pub thumbnail_info: Option<Box<ThumbnailInfo>>,
    pub thumbnail_source: Option<MediaSource>,
    pub blurhash: Option<String>,
    pub thumbhash: Option<Base64>,
    pub is_animated: Option<bool>,
}

Metadata about an image.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

height: Option<UInt>

The height of the image in pixels.

width: Option<UInt>

The width of the image in pixels.

mimetype: Option<String>

The MIME type of the image, e.g. “image/png.”

size: Option<UInt>

The file size of the image in bytes.

thumbnail_info: Option<Box<ThumbnailInfo>>

Metadata about the image referred to in thumbnail_source.

thumbnail_source: Option<MediaSource>

The source of the thumbnail of the image.

blurhash: Option<String>

The BlurHash for this image.

This uses the unstable prefix in MSC2448.

thumbhash: Option<Base64>

The ThumbHash for this image.

This uses the unstable prefix in MSC2448.

is_animated: Option<bool>

If this flag is true, the original image SHOULD be assumed to be animated. If this flag is false, the original image SHOULD be assumed to NOT be animated.

If a sending client is unable to determine whether an image is animated, it SHOULD leave the flag unset.

Receiving clients MAY use this flag to optimize whether to download the original image rather than a thumbnail if it is animated, but they SHOULD NOT trust this flag.
