Struct SessionState

#[non_exhaustive]
pub struct SessionState {
    pub dialog_action: Option<DialogAction>,
    pub intent: Option<Intent>,
    pub active_contexts: Option<Vec<ActiveContext>>,
    pub session_attributes: Option<HashMap<String, String>>,
    pub originating_request_id: Option<String>,
    pub runtime_hints: Option<RuntimeHints>,
}

The state of the user's session with Amazon Lex V2.

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.

dialog_action: Option<DialogAction>

The next step that Amazon Lex V2 should take in the conversation with a user.

intent: Option<Intent>

The active intent that Amazon Lex V2 is processing.

active_contexts: Option<Vec<ActiveContext>>

One or more contexts that indicate to Amazon Lex V2 the context of a request. When a context is active, Amazon Lex V2 considers intents with the matching context as a trigger as the next intent in a session.

session_attributes: Option<HashMap<String, String>>

Map of key/value pairs representing session-specific context information. It contains application information passed between Amazon Lex V2 and a client application.

originating_request_id: Option<String>

A unique identifier for a specific request.

runtime_hints: Option<RuntimeHints>

Hints for phrases that a customer is likely to use for a slot. Amazon Lex V2 uses the hints to help determine the correct value of a slot.

Implementations

impl SessionState

pub fn dialog_action(&self) -> Option<&DialogAction>

The next step that Amazon Lex V2 should take in the conversation with a user.

pub fn intent(&self) -> Option<&Intent>

The active intent that Amazon Lex V2 is processing.

pub fn active_contexts(&self) -> &[ActiveContext]

One or more contexts that indicate to Amazon Lex V2 the context of a request. When a context is active, Amazon Lex V2 considers intents with the matching context as a trigger as the next intent in a session.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .active_contexts.is_none().

pub fn session_attributes(&self) -> Option<&HashMap<String, String>>

Map of key/value pairs representing session-specific context information. It contains application information passed between Amazon Lex V2 and a client application.

pub fn originating_request_id(&self) -> Option<&str>

A unique identifier for a specific request.

pub fn runtime_hints(&self) -> Option<&RuntimeHints>

Hints for phrases that a customer is likely to use for a slot. Amazon Lex V2 uses the hints to help determine the correct value of a slot.

impl SessionState

pub fn builder() -> SessionStateBuilder

Creates a new builder-style object to manufacture SessionState.

Trait Implementations

impl Clone for SessionState

fn clone(&self) -> SessionState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionState

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

Formats the value using the given formatter.

impl PartialEq for SessionState

fn eq(&self, other: &SessionState) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
