Implementations
sourceimpl<'a> GuardContext<'a>
impl<'a> GuardContext<'a>
sourcepub fn head(&self) -> &RequestHead
pub fn head(&self) -> &RequestHead
Returns reference to the request head.
sourcepub fn req_data(&self) -> Ref<'a, Extensions>
pub fn req_data(&self) -> Ref<'a, Extensions>
Returns reference to the request-local data/extensions container.
sourcepub fn req_data_mut(&self) -> RefMut<'a, Extensions>
pub fn req_data_mut(&self) -> RefMut<'a, Extensions>
Returns mutable reference to the request-local data/extensions container.
sourcepub fn header<H: Header>(&self) -> Option<H>
pub fn header<H: Header>(&self) -> Option<H>
Extracts a typed header from the request.
Returns None
if parsing H
fails.
Examples
use actix_web::{guard::fn_guard, http::header};
let image_accept_guard = fn_guard(|ctx| {
match ctx.header::<header::Accept>() {
Some(hdr) => hdr.preference() == "image/*",
None => false,
}
});
