A trait for a type that has specific implementations of package script evaluation functions

Required Associated Types

type Shared<'a>

The shared evaluation state to provide to methods

type VariableStore: VariableStore

The type of variable store to use

Required Methods

fn get_variable_store<'a>( &self, shared: &'a mut Self::Shared<'_>, ) -> &'a mut Self::VariableStore

Get the evaluator’s variable store from the shared data

fn eval_condition( &mut self, shared: &mut Self::Shared<'_>, condition: &ConditionKind, ) -> Result<bool>

Evaluate a condition

fn add_dependency( &mut self, shared: &mut Self::Shared<'_>, dep: Vec<RequiredPackage>, ) -> Result<()>

Add a dependency

fn add_conflict( &mut self, shared: &mut Self::Shared<'_>, pkg: PackageID, ) -> Result<()>

Add a conflict

fn add_recommendation( &mut self, shared: &mut Self::Shared<'_>, pkg: RecommendedPackage, ) -> Result<()>

Add a recommendation

fn add_bundled( &mut self, shared: &mut Self::Shared<'_>, pkg: PackageID, ) -> Result<()>

Add a bundled package

fn add_compat( &mut self, shared: &mut Self::Shared<'_>, compat: (PackageID, PackageID), ) -> Result<()>

Add a compat

fn add_extension( &mut self, shared: &mut Self::Shared<'_>, pkg: PackageID, ) -> Result<()>

Add an extension

fn add_notice( &mut self, shared: &mut Self::Shared<'_>, notice: String, ) -> Result<()>

Add a notice

fn add_command( &mut self, shared: &mut Self::Shared<'_>, command: Vec<String>, ) -> Result<()>

Add a command

fn add_addon( &mut self, shared: &mut Self::Shared<'_>, addon: AddonInstructionData, ) -> Result<()>

Add an addon

fn run_custom( &mut self, shared: &mut Self::Shared<'_>, command: String, args: Vec<String>, ) -> Result<()>

Run a custom instruction

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.
