Struct WhenView 

#[non_exhaustive]
pub struct WhenView {
    pub url_path: Option<UrlPathView>,
    pub method: Option<String>,
    pub has_header_conditions: bool,
    pub has_body_conditions: bool,
}

Structured representation of a rule’s when clause (spec §5.3).

Why each field is Option

A rule with when.request.url_path = "/api" and no other clauses matches every request whose URL is /api, regardless of method or headers. Carrying explicit Nones for unset fields keeps the distinction between “not constrained” and “constrained to empty” — the GUI renders the former as a blank field and the latter as “method = (none)”.

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.

url_path: Option<UrlPathView>

URL-path predicate as written in the rule. Carries the matching operator (equals / starts_with / contains / wild_card / pattern).

method: Option<String>

HTTP method — uppercase string like "GET" to match the underlying HttpMethod::as_str() representation.

has_header_conditions: bool

true iff the rule restricts on request headers. We don’t surface the actual header conditions yet (the routing crate’s Headers type isn’t publicly inspectable at this stage); the boolean tells the GUI whether to render a “headers constraint present” badge.

has_body_conditions: bool

true iff the rule restricts on request body JSON.

Implementations

impl WhenView

pub fn summary(&self) -> String

Compact human-readable summary built from the populated fields in priority order (method → path → constraint badges).

impl Default for WhenView

fn default() -> WhenView

Returns the “default value” for a type.
