Struct SessionId 

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

Opaque handle that uniquely identifies an execution session across all verb calls.

SessionId is a newtype over String and is the sole cross-boundary handle needed to address a session. Generation is the responsibility of the engine layer; the core value layer only provides construction and inspection primitives.

Serde

Serializes as a plain JSON string (transparent newtype) so that wire consumers do not need to unwrap a wrapper object.

Implementations

impl SessionId

pub fn new(s: String) -> Self

Wraps an existing string as a SessionId.

pub fn generate() -> Self

Generate a new unique SessionId.

Uses Unix milliseconds combined with a process-global counter to ensure uniqueness within a process even at sub-millisecond resolution. Format: "ses-{ms}-{counter}".

pub fn as_str(&self) -> &str

Returns the inner string value.

Trait Implementations

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<'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 Eq for SessionId

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.
