Struct BodyMutation 

pub struct BodyMutation {
    pub data: Option<String>,
    pub chunk_index: u32,
}

Body mutation from agent

Allows agents to modify body content during streaming:

• None data: pass through original chunk unchanged
• Some(empty): drop the chunk entirely
• Some(data): replace chunk with modified content

Fields

data: Option<String>

Modified body data (base64 encoded for JSON transport)

• None: use original chunk unchanged
• Some(""): drop this chunk
• Some(data): replace chunk with this data

chunk_index: u32

Chunk index this mutation applies to

Must match the chunk_index from the body chunk event.

Implementations

impl BodyMutation

pub fn pass_through(chunk_index: u32) -> Self

Create a pass-through mutation (no change)

pub fn drop_chunk(chunk_index: u32) -> Self

Create a mutation that drops the chunk

pub fn replace(chunk_index: u32, data: String) -> Self

Create a mutation that replaces the chunk

pub fn is_pass_through(&self) -> bool

Check if this mutation passes through unchanged

pub fn is_drop(&self) -> bool

Check if this mutation drops the chunk

Trait Implementations

impl Clone for BodyMutation

fn clone(&self) -> BodyMutation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BodyMutation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BodyMutation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BodyMutation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for BodyMutation
