Struct RequestState 

pub struct RequestState<T = ()> {
    pub headers: Vec<HeaderEntry>,
    pub sent_at_unix_ms: i64,
    pub interface_id: u32,
    pub method_id: u32,
    pub custom: T,
    /* private fields */
}

Request state passed to handlers

Contains request metadata and custom per-request state that can be set by middlewares and accessed by handlers.

Fields

headers: Vec<HeaderEntry>

Request headers

sent_at_unix_ms: i64

When the request was sent (unix milliseconds)

interface_id: u32

Interface ID being called

method_id: u32

Method ID being called

custom: T

Custom service-specific state (set by middlewares)

Implementations

impl<T> RequestState<T>

pub fn from_request(request: &RpcRequest, custom: T) -> Self

pub fn set_extension<V: Any + Send + Sync>( &mut self, key: impl Into<String>, value: V, )

Set an extension value

pub fn get_extension<V: Any + Send + Sync>(&self, key: &str) -> Option<&V>

Get an extension value

pub fn get_extension_mut<V: Any + Send + Sync>( &mut self, key: &str, ) -> Option<&mut V>

Get a mutable extension value

pub fn get_header(&self, key: u32) -> Option<&HeaderEntry>
