Struct SessionId 

pub struct SessionId(/* private fields */);

Unique identifier for a Claude Code session.

Wraps a UUID string (e.g., “8e11bfb5-7dc2-432b-9206-928fa5c35731”). Obtained from Claude Code’s status line JSON session_id field.

Implementations

impl SessionId

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

Creates a new SessionId from a string.

Note: This does not validate UUID format. Claude Code provides the session_id, so we trust its format.

pub fn pending_from_pid(pid: u32) -> Self

Creates a pending session ID from a process ID.

Used when a Claude process is discovered but no transcript exists yet (e.g., session just started, no conversation has occurred). The pending session will be upgraded to the real session ID when it arrives via hook event or status line.

pub fn is_pending(&self) -> bool

Checks if this is a pending session ID (not yet associated with real session).

pub fn pending_pid(&self) -> Option<u32>

Extracts the PID from a pending session ID.

Returns None if this is not a pending session ID or the PID cannot be parsed.

pub fn as_str(&self) -> &str

Returns the underlying string reference.

pub fn short(&self) -> &str

Returns a shortened display form (first 8 characters).

Useful for compact TUI display.

Trait Implementations

impl AsRef<str> for SessionId

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for SessionId

fn clone(&self) -> SessionId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionId

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

Formats the value using the given formatter.

impl Default for SessionId

fn default() -> SessionId

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SessionId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SessionId

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

Formats the value using the given formatter.

impl From<&str> for SessionId

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for SessionId

fn from(s: String) -> Self

Converts to this type from the input type.

impl Hash for SessionId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SessionId

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

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 SessionId
