Struct HostFunctionPolicy 

pub struct HostFunctionPolicy { /* private fields */ }

Host function policy used before running a WASM capability.

Implementations

impl HostFunctionPolicy

pub fn pure() -> Self

Returns the default pure profile that denies all ambient host imports.

pub fn allowing( profile: impl Into<String>, imports: impl IntoIterator<Item = impl Into<String>>, ) -> Self

Returns a profile with an explicit allowlist of host imports.

pub fn evaluate(&self, target: &ModuleTargetDescriptor) -> HostImportReport

Evaluates a target’s requested host imports against this policy.

pub fn reject_unavailable_imports_before_execution( &self, target: &ModuleTargetDescriptor, ) -> Result<HostImportReport, ModuleCapabilityError>

Rejects a target before execution when required host imports are unavailable.

Trait Implementations

impl Clone for HostFunctionPolicy

fn clone(&self) -> HostFunctionPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HostFunctionPolicy

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

Formats the value using the given formatter.

impl Eq for HostFunctionPolicy

impl PartialEq for HostFunctionPolicy

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
