Struct ResourceInfo 

#[non_exhaustive]
pub struct ResourceInfo {
    pub uri: String,
    pub name: String,
    pub title: Option<String>,
    pub description: Option<String>,
    pub mime_type: Option<String>,
    pub icons: Option<Vec<IconInfo>>,
    pub annotations: Option<Annotations>,
    pub meta: Option<Map<String, Value>>,
}

Resource information.

Construction

Use ResourceInfo::new for ergonomic construction:

use pmcp::types::ResourceInfo;

let resource = ResourceInfo::new("file://test.txt", "test.txt")
    .with_description("A test file")
    .with_mime_type("text/plain");

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.

uri: String

Resource URI

name: String

Human-readable name

title: Option<String>

Optional human-readable title (MCP 2025-11-25)

description: Option<String>

Resource description

mime_type: Option<String>

MIME type

icons: Option<Vec<IconInfo>>

Optional icons (MCP 2025-11-25)

annotations: Option<Annotations>

Optional content annotations (MCP 2025-11-25)

meta: Option<Map<String, Value>>

Optional metadata (e.g., widget descriptor keys for ChatGPT MCP Apps)

Implementations

impl ResourceInfo

pub fn new(uri: impl Into<String>, name: impl Into<String>) -> Self

Create a new resource with the required URI and name fields.

All optional fields default to None.

pub fn with_title(self, title: impl Into<String>) -> Self

Set the human-readable title.

pub fn with_description(self, description: impl Into<String>) -> Self

Set the resource description.

pub fn with_mime_type(self, mime_type: impl Into<String>) -> Self

Set the MIME type.

pub fn with_icons(self, icons: Vec<IconInfo>) -> Self

Set the resource icons.

pub fn with_annotations(self, annotations: Annotations) -> Self

Set content annotations.

pub fn with_meta(self, meta: Map<String, Value>) -> Self

Set metadata (e.g., widget descriptor keys for MCP Apps).
