Struct ResourceReference 

pub struct ResourceReference {
    pub uri: String,
    pub name: String,
    pub title: Option<String>,
    pub description: Option<String>,
    pub mime_type: Option<String>,
    pub size: Option<u64>,
    pub icons: Option<Vec<Icon>>,
    pub annotations: Option<Annotations>,
    pub meta: Option<HashMap<String, Value>>,
}

Core MCP protocol types and error handling Resource reference for resource links.

Mirrors the schema’s Resource interface so ContentBlock::ResourceLink (which the schema declares as ResourceLink extends Resource) round-trips all spec-permitted fields including size and icons.

Carries the same fields as crate::resources::Resource; the parallel type is preserved for now because ContentBlock::ResourceLink flattens this body and we don’t want to cascade the type swap through prompts.rs/lib.rs re-exports in this slice. Collapsing onto a single Resource struct is the cleaner end-state.

Fields

uri: String

The URI of this resource

name: String

A human-readable name for this resource

title: Option<String>

A human-readable title for this resource

description: Option<String>

A description of what this resource represents or contains

mime_type: Option<String>

The MIME type of this resource, if known

size: Option<u64>

Size of the raw resource content, in bytes. Hosts use this for file-size display and context-window estimation.

icons: Option<Vec<Icon>>

Display icons (from Resource extends Icons). Most consumers won’t need this.

annotations: Option<Annotations>

Client annotations for this resource

meta: Option<HashMap<String, Value>>

Additional metadata for this resource
