Trait for a central package registry that can evaluate packages

Required Associated Types

type CommonInput

Type passed to most functions, used for common / cached values

type EvalInput<'b>: Clone

Type passed to the evaluation function

type EvalRelationsResult<'b>: PackageEvalRelationsResult

Result from package relationship evaluation

type ConfiguredPackage: ConfiguredPackage<EvalInput<'a> = Self::EvalInput<'a>>

Configured package type

Required Methods

fn eval_package_relations<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 mut self, pkg: &'life1 ArcPkgReq, input: &'life2 Self::EvalInput<'a>, common_input: &'life3 Self::CommonInput, ) -> Pin<Box<dyn Future<Output = Result<Self::EvalRelationsResult<'a>>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Evaluate the relationships of a package

fn get_package_properties<'b, 'life0, 'life1, 'async_trait>( &'b mut self, pkg: &'life0 ArcPkgReq, common_input: &'life1 Self::CommonInput, ) -> Pin<Box<dyn Future<Output = Result<&'b PackageProperties>> + Send + 'async_trait>>

where Self: 'async_trait, 'b: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get the properties of a package

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
