Struct BrowserPreHookCtx 

#[non_exhaustive]
pub struct BrowserPreHookCtx<'a> {
    pub request: &'a Request,
    pub page: &'a PageHandle,
    pub session: Option<&'a Session>,
    pub proxy: Option<&'a ProxyInfo>,
}

Context supplied to browser pre-navigation hooks.

Unlike the INTERFACE §18 sketch, request is immutable because execution owns an Arc<Request>. The proposed log field is omitted because no Log type exists; use tracing macros instead. This context is non-exhaustive so log can be added later without a breaking change.

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.

request: &'a Request

Request about to be navigated.

page: &'a PageHandle

Live page that will perform the navigation.

session: Option<&'a Session>

Session selected for this attempt, when sessions are enabled.

proxy: Option<&'a ProxyInfo>

Proxy assigned to the browser containing the page.
