Struct Icon 

pub struct Icon {
    pub src: Option<String>,
    pub mime_type: Option<String>,
    pub sizes: Option<String>,
}

Icon metadata for visual representation of components.

Icons provide visual representation for tools, resources, and prompts in client UIs. All fields are optional to support various use cases.

Fields

src: Option<String>

URL or data URI for the icon.

Can be:

• HTTP/HTTPS URL: https://example.com/icon.png
• Data URI: data:image/png;base64,iVBORw0KGgo...

mime_type: Option<String>

MIME type of the icon (e.g., “image/png”, “image/svg+xml”).

sizes: Option<String>

Size hints for the icon (e.g., “32x32”, “16x16 32x32 64x64”).

Implementations

impl Icon

pub fn new(src: impl Into<String>) -> Self

Creates a new icon with just a source URL.

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

Creates a new icon with source and MIME type.

pub fn full( src: impl Into<String>, mime_type: impl Into<String>, sizes: impl Into<String>, ) -> Self

Creates a new icon with all fields.

pub fn has_src(&self) -> bool

Returns true if this icon has a source.

pub fn is_data_uri(&self) -> bool

Returns true if the source is a data URI.

Trait Implementations

impl Clone for Icon

fn clone(&self) -> Icon

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Icon

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Icon

fn default() -> Icon

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Icon

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Icon

fn eq(&self, other: &Icon) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Icon

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
