Struct MetaMap 

pub struct MetaMap { /* private fields */ }

Typed metadata bag for routes/routers (one value per TypeId; last insert wins).

Implementations

impl MetaMap

pub fn new() -> Self

pub fn insert<T: RouteValue>(&mut self, value: T)

pub fn get<T: RouteValue>(&self) -> Option<Arc<T>>

pub fn extend(&mut self, other: MetaMap)

Merge another map; later values overwrite the same TypeId.

pub fn is_empty(&self) -> bool

pub fn check_all(&self, ctx: &BuildCtx<'_>) -> Result<(), String>

pub fn labels(&self) -> Vec<&str>

Labels for introspection (stable order by label string).

fn clone(&self) -> MetaMap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for MetaMap

fn default() -> MetaMap
