Struct UrlPreview

Source 
#[non_exhaustive]
pub struct UrlPreview {
    pub matched_url: Option<String>,
    pub url: Option<String>,
    pub title: Option<String>,
    pub description: Option<String>,
    pub image: Option<PreviewImage>,

Available on crate feature events only.
Expand description

Preview Information for a URL matched in the message’s text, according to MSC 4095.

Fields (Non-exhaustive)§

This struct is marked as 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.
§matched_url: Option<String>

The url this was matching on.

§url: Option<String>

Canonical URL according to open graph data.

§title: Option<String>

Title to use for the preview.

§description: Option<String>

Description to use for the preview.

§image: Option<PreviewImage>

Metadata of a preview image if given.
