Struct PromptMessage 

#[non_exhaustive]
pub struct PromptMessage {
    pub role: PromptMessageRole,
    pub content: PromptMessageContent,
}

Re-exports of the rmcp wire-protocol types this crate now surfaces directly instead of wrapping. Pull these in to pattern-match on tool annotations, content blocks, structured tool output, embedded resources, sampling / elicitation requests, progress and log notifications, etc. A message in a prompt conversation

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.

role: PromptMessageRole

The role of the message sender

content: PromptMessageContent

The content of the message

Implementations

impl PromptMessage

pub fn new( role: PromptMessageRole, content: PromptMessageContent, ) -> PromptMessage

Create a new prompt message with the given role and content

pub fn new_text<S>(role: PromptMessageRole, text: S) -> PromptMessage

where S: Into<String>,

Create a new text message with the given role and text content

pub fn new_resource( role: PromptMessageRole, uri: String, mime_type: Option<String>, text: Option<String>, resource_meta: Option<Meta>, resource_content_meta: Option<Meta>, annotations: Option<Annotations>, ) -> PromptMessage

Create a new resource message. resource_meta, resource_content_meta, and annotations are optional.

pub fn new_text_with_meta<S>( role: PromptMessageRole, text: S, _meta: Option<Meta>, ) -> PromptMessage

where S: Into<String>,

Note: PromptMessage text content does not carry protocol-level _meta per current schema. This function exists for API symmetry but ignores the meta parameter.

pub fn new_resource_link( role: PromptMessageRole, resource: Annotated<RawResource>, ) -> PromptMessage

Create a new resource link message

Trait Implementations

impl Clone for PromptMessage

fn clone(&self) -> PromptMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PromptMessage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PromptMessage

fn deserialize<__D>( __deserializer: __D, ) -> Result<PromptMessage, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PromptMessage

fn eq(&self, other: &PromptMessage) -> 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 PromptMessage

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
