Enum Block 

pub enum Block {
    Text(String),
    Reasoning(String),
    ToolCall {
        id: String,
        title: String,
        status: ToolStatus,
        kind: ToolKind,
        input: Option<String>,
        output: Option<String>,
    },
    Edit {
        path: String,
        status: EditStatus,
    },
    Permission {
        id: String,
        title: String,
        description: Option<String>,
        options: Vec<PermissionOption>,
        status: PermissionStatus,
    },
}

One renderable unit within a turn.

Variants

Text(String)

Streamed message text.

Reasoning(String)

Streamed reasoning / thinking. TCF: the projection prefixes each line with │, and a multi-line block is folded closed by default via ReasoningFoldSource — the fold keeps the head line visible and hides the rest until za. (Before TCF this comment claimed folding the projection did not do.)

ToolCall

A tool invocation and its live status.

TCF: kind, input and output are the detail an expanded tool call shows. input/output are the agent’s raw JSON, pretty-printed at ingest (stored as String, not serde_json::Value, so Block stays Eq). Detail commonly arrives on a later ToolCallUpdate, not the initial call, so it is merged in as it lands.

Fields

id: String

title: String

status: ToolStatus

kind: ToolKind

input: Option<String>

output: Option<String>

Edit

An agent-proposed file edit (AU‑4 wires the diff review).

Fields

path: String

status: EditStatus

Permission

AUX‑1: an inline permission request awaiting or reflecting user action.

Fields

id: String

title: String

description: Option<String>

options: Vec<PermissionOption>

status: PermissionStatus
