Struct Callback 

pub struct Callback {
    pub name: String,
    pub expression: String,
    pub operation_ids: Vec<String>,
    pub extensions: Vec<(String, ValueRef)>,
}

OAS Callback Object — describes out-of-band requests the API makes back to the caller. Used heavily by event-driven and webhook APIs.

The OAS shape is callbacks: { <name>: { <expression>: PathItem } } (a name maps to a map of runtime expressions, each pointing to a path item). The IR flattens this: each Callback carries one (name, expression) pair plus the ids of the operations the path item declared. A callback name with multiple expressions becomes multiple Callback entries with the same name.

operation_ids reference into Ir::operations — callback path- item operations live in the same flat list as top-level paths so the WIT shape stays non-recursive. OAS operationId uniqueness is API-wide, so this is consistent with the spec.

Fields

name: String

expression: String

Runtime expression keyed by the path-item entry, e.g. {$request.body#/callbackUrl}. Verbatim from the spec.

operation_ids: Vec<String>

Ids referencing into Ir::operations.

extensions: Vec<(String, ValueRef)>

Trait Implementations

impl Clone for Callback

fn clone(&self) -> Callback

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Callback

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Callback

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Callback

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
