Struct CorsPolicy 

pub struct CorsPolicy {
    pub fields: Vec<CorsField>,
    pub span: Span,
    pub trivia: Trivia,
}

A cross-origin resource-sharing policy on a from http service (v0.131, ADR 0159): the cors { } section in the service body. Parsed leniently as a list of name: value fields (the grammar accepts any field name — an unknown one is a checker diagnostic, per the @-annotation precedent, ADR 0111), and interpreted through the typed accessors below.

Access-Control-Allow-Methods is deliberately not a field — it is derived from the service’s routes at emit time (the routes already enumerate the methods; a restated list would drift). Likewise Allow-Headers defaults to content-type (+ Authorization when a Bearer route exists) and is only stored here when the author overrides it.

Fields

fields: Vec<CorsField>

The cors { } fields as written, in source order. Field names are validated against the closed set (origins/headers/credentials/ maxAge) by the checker, not the parser.

span: Span

trivia: Trivia

Implementations

impl CorsPolicy

pub fn field(&self, name: &str) -> Option<&Expr>

The raw value expression for a field, by name (the last one wins if a field is repeated — the checker flags the duplicate separately).

pub fn origins(&self) -> Vec<String>

The allowed origins — the string literals of the origins: list. An absent or malformed field yields an empty list (the checker has already reported the shape error; the emitter fails closed on an empty list).

pub fn is_wildcard(&self) -> bool

true iff origins is exactly the wildcard ["*"].

pub fn credentials(&self) -> bool

Whether credentialed requests are allowed (credentials: true); defaults to false when the field is absent.

pub fn allow_headers(&self) -> Option<Vec<String>>

The explicit Access-Control-Allow-Headers override, if the author gave a headers: list; None leaves the emitter to apply its smart default.

pub fn max_age_secs(&self) -> Option<i64>

The Access-Control-Max-Age in whole seconds, if a maxAge: duration was given; None leaves the header off (the browser default).
