}

Server-policy resource limits. A caller may request smaller limits through LimitsOverride but can never raise them above server policy.

Implementations

impl Limits

pub fn conservative() -> Limits

Documented conservative defaults. See docs/limits.md for rationale.

pub fn lowered_by( &self, overrides: &LimitsOverride, ) -> Result<Limits, EngineError>

Effective limits after applying caller-requested reductions.

Returns an error when the caller asks for a limit above server policy.

pub fn deadline(&self) -> Option<Instant>

Compute a wall-clock deadline from the timeout.

WASM has no portable monotonic clock through std, so browser builds run without a wall-clock deadline; operation budgets and cooperative cancellation still bound work.

Trait Implementations

impl Clone for Limits

fn clone(&self) -> Limits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Limits

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

Formats the value using the given formatter.

impl Default for Limits

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Limits

where Limits: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Limits

impl From<&Limits> for AppliedLimits

fn from(limits: &Limits) -> Self

Converts to this type from the input type.

impl PartialEq for Limits

fn eq(&self, other: &Limits) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for Limits

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
