Enum BlockDelta 

pub enum BlockDelta {
    Text(String),
    Thinking(String),
    InputJson(String),
    Other,
}

The incremental payload carried by a PartialMessageEvent::BlockDelta.

Mirrors the delta.type field from the Anthropic streaming API. Less-common delta kinds (signature, citations, compaction, …) collapse to BlockDelta::Other; callers that need them can fall back to StreamEvent::data.

Variants

Text(String)

Chunk of assistant text.

Thinking(String)

Chunk of extended-thinking text.

InputJson(String)

Chunk of streaming tool-input JSON. Concatenate across deltas to reconstruct the full input – individual chunks are not standalone JSON.

Other

Any delta type not modelled above (e.g. signature_delta, citations_delta). Read from StreamEvent::data for the raw payload.

Trait Implementations

impl Clone for BlockDelta

fn clone(&self) -> BlockDelta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockDelta

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

Formats the value using the given formatter.

impl PartialEq for BlockDelta

fn eq(&self, other: &BlockDelta) -> 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.
