Struct ResourceLink 

pub struct ResourceLink {
    pub uri: Uri,
    pub name: String,
    pub size: Option<usize>,
    pub mime: Option<String>,
    pub title: Option<String>,
    pub descr: Option<String>,
    pub annotations: Option<Annotations>,
    pub icons: Option<Vec<Icon>>,
    pub meta: Option<Value>,
}

A resource that the server is capable of reading, included in a prompt or tool call result.

Note: resource links returned by tools are not guaranteed to appear in the results of resources/list requests.

See the schema for details

Fields

uri: Uri

The URI of this resource.

name: String

Intended for programmatic or logical use
but used as a display name in past specs or fallback (if a title isn’t present).

size: Option<usize>

The resource size in bytes, if known

mime: Option<String>

The MIME type of the resource. If known.

title: Option<String>

Intended for UI and end-user contexts - optimized to be human-readable and easily understood, even by those unfamiliar with domain-specific terminology.

If not provided, the name should be used for display (except for Tool, where annotations.title should be given precedence over using name, if present).

descr: Option<String>

A description of what this resource represents.

annotations: Option<Annotations>

Optional annotations for the client.

icons: Option<Vec<Icon>>

Optional set of sized icons that the client can display in a user interface.

Clients that support rendering icons MUST support at least the following MIME types:

• image/png - PNG images (safe, universal compatibility)
• image/jpeg (and image/jpg) - JPEG images (safe, universal compatibility)

Clients that support rendering icons SHOULD also support:

• image/svg+xml - SVG images (scalable but requires security precautions)
• image/webp - WebP images (modern, efficient format)

meta: Option<Value>

Metadata reserved by MCP for protocol-level metadata.
