Struct ScopeLayer 

pub struct ScopeLayer { /* private fields */ }

Available on crate feature std only.

Runs every input in its own child Scope, see the module docs.

Implementations

impl ScopeLayer

pub const fn new() -> ScopeLayer

A layer that only gives every input its own child scope.

pub fn maybe_with_parent(self, parent: Option<WeakScope>) -> ScopeLayer

Also run every input in parent, such as the scope of the server that serves it, besides the scope the input already runs in. The layer does not hold it: an input arriving once it is closed is refused.

pub fn maybe_set_parent(&mut self, parent: Option<WeakScope>) -> &mut ScopeLayer

Also run every input in parent, such as the scope of the server that serves it, besides the scope the input already runs in. The layer does not hold it: an input arriving once it is closed is refused.

pub fn with_parent(self, parent: WeakScope) -> ScopeLayer

Also run every input in parent, such as the scope of the server that serves it, besides the scope the input already runs in. The layer does not hold it: an input arriving once it is closed is refused.

pub fn set_parent(&mut self, parent: WeakScope) -> &mut ScopeLayer

Also run every input in parent, such as the scope of the server that serves it, besides the scope the input already runs in. The layer does not hold it: an input arriving once it is closed is refused.

pub fn without_parent(self) -> ScopeLayer

Also run every input in parent, such as the scope of the server that serves it, besides the scope the input already runs in. The layer does not hold it: an input arriving once it is closed is refused.

pub fn unset_parent(&mut self) -> &mut ScopeLayer

Also run every input in parent, such as the scope of the server that serves it, besides the scope the input already runs in. The layer does not hold it: an input arriving once it is closed is refused.

pub fn maybe_with_max_age(self, max_age: Option<Duration>) -> ScopeLayer

Cancel the scope of an input this long after it started.

pub fn maybe_set_max_age( &mut self, max_age: Option<Duration>, ) -> &mut ScopeLayer

Cancel the scope of an input this long after it started.

pub fn with_max_age(self, max_age: Duration) -> ScopeLayer

Cancel the scope of an input this long after it started.

pub fn set_max_age(&mut self, max_age: Duration) -> &mut ScopeLayer

Cancel the scope of an input this long after it started.

pub fn without_max_age(self) -> ScopeLayer

Cancel the scope of an input this long after it started.

pub fn unset_max_age(&mut self) -> &mut ScopeLayer

Cancel the scope of an input this long after it started.

pub fn with_max_age_jitter(self, jitter: f64) -> ScopeLayer

Spread the max age of each input uniformly within ± this fraction of it, so inputs that started together do not all drain at once. Clamped to 0.0..=1.0; zero, the default, keeps every max age exact.

pub fn set_max_age_jitter(&mut self, jitter: f64) -> &mut ScopeLayer

Spread the max age of each input uniformly within ± this fraction of it, so inputs that started together do not all drain at once. Clamped to 0.0..=1.0; zero, the default, keeps every max age exact.

pub fn maybe_with_grace(self, grace: Option<Duration>) -> ScopeLayer

Abort the scope of an input this long after it is cancelled, for any cause.

pub fn maybe_set_grace(&mut self, grace: Option<Duration>) -> &mut ScopeLayer

Abort the scope of an input this long after it is cancelled, for any cause.

pub fn with_grace(self, grace: Duration) -> ScopeLayer

Abort the scope of an input this long after it is cancelled, for any cause.

pub fn set_grace(&mut self, grace: Duration) -> &mut ScopeLayer

Abort the scope of an input this long after it is cancelled, for any cause.

pub fn without_grace(self) -> ScopeLayer

Abort the scope of an input this long after it is cancelled, for any cause.

pub fn unset_grace(&mut self) -> &mut ScopeLayer

Abort the scope of an input this long after it is cancelled, for any cause.

pub fn maybe_with_hard_max_age( self, hard_max_age: Option<Duration>, ) -> ScopeLayer

Abort the scope of an input this long after it started.

pub fn maybe_set_hard_max_age( &mut self, hard_max_age: Option<Duration>, ) -> &mut ScopeLayer

Abort the scope of an input this long after it started.

pub fn with_hard_max_age(self, hard_max_age: Duration) -> ScopeLayer

Abort the scope of an input this long after it started.

pub fn set_hard_max_age(&mut self, hard_max_age: Duration) -> &mut ScopeLayer

Abort the scope of an input this long after it started.

pub fn without_hard_max_age(self) -> ScopeLayer

Abort the scope of an input this long after it started.

pub fn unset_hard_max_age(&mut self) -> &mut ScopeLayer

Abort the scope of an input this long after it started.

Trait Implementations

impl Clone for ScopeLayer

fn clone(&self) -> ScopeLayer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScopeLayer

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ScopeLayer

fn default() -> ScopeLayer

Returns the “default value” for a type.

impl<S> Layer<S> for ScopeLayer

type Service = ScopeService<S>

The service produced by the layer.

fn layer(&self, inner: S) -> <ScopeLayer as Layer<S>>::Service

Wrap the given service with the middleware, returning a new service.

fn into_layer(self, inner: S) -> <ScopeLayer as Layer<S>>::Service

Same as layer but consuming self after the service was created.
