Struct Part 

pub struct Part {
    pub text: Option<String>,
    pub raw: Option<String>,
    pub url: Option<String>,
    pub data: Option<Value>,
    pub metadata: Option<Value>,
    pub filename: Option<String>,
    pub media_type: Option<String>,
}

Part content — flat struct matching proto3 oneof serialization.

Exactly one content field (text, raw, url, or data) should be set. Shared fields (metadata, filename, media_type) can accompany any content type.

Fields

text: Option<String>

Text content (plain text or markdown)

raw: Option<String>

Raw bytes content (base64-encoded)

url: Option<String>

URL reference to content

data: Option<Value>

Structured JSON data

metadata: Option<Value>

Part-level metadata

filename: Option<String>

Optional filename

media_type: Option<String>

MIME type (e.g., “text/plain”, “image/png”, “application/json”)

Implementations

impl Part

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

Create a text part

pub fn url(url: impl Into<String>, media_type: impl Into<String>) -> Self

Create a URL reference part

pub fn data(data: Value, media_type: impl Into<String>) -> Self

Create a structured data part

pub fn raw(raw: impl Into<String>, media_type: impl Into<String>) -> Self

Create a raw bytes part (base64-encoded)

Trait Implementations

impl Clone for Part

fn clone(&self) -> Part

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Part

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Part

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Part

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
