Struct ForkSessionRequest 

#[non_exhaustive]
pub struct ForkSessionRequest {
    pub session_id: SessionId,
    pub cwd: PathBuf,
    pub additional_directories: Vec<PathBuf>,
    pub mcp_servers: Vec<McpServer>,
    pub meta: Option<Meta>,
}

UNSTABLE

This capability is not part of the spec yet, and may be removed or changed at any point.

Request parameters for forking an existing session.

Creates a new session based on the context of an existing one, allowing operations like generating summaries without affecting the original session’s history.

Only available if the Agent supports the session.fork capability.

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.

session_id: SessionId

The ID of the session to fork.

cwd: PathBuf

The working directory for this session.

additional_directories: Vec<PathBuf>

Additional workspace roots to activate for this session. Each path must be absolute.

When omitted or empty, no additional roots are activated. When non-empty, this is the complete resulting additional-root list for the forked session.

mcp_servers: Vec<McpServer>

List of MCP servers to connect to for this session.

meta: Option<Meta>

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. Implementations MUST NOT make assumptions about values at these keys.

See protocol docs: Extensibility

Trait Implementations

impl Clone for ForkSessionRequest

fn clone(&self) -> ForkSessionRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ForkSessionRequest

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ForkSessionRequest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ForkSessionRequest

impl IntoV2 for ForkSessionRequest

Available on crate features unstable_protocol_v2 and unstable_session_fork only.

type Output = ForkSessionRequest

The corresponding v2 draft type.

fn into_v2(self) -> Result<Self::Output>

Converts this value into the corresponding v2 draft type.

impl JsonSchema for ForkSessionRequest

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for ForkSessionRequest

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
