Struct arithmetic_eval::CallContext

pub struct CallContext<'r, T> { /* private fields */ }

Context for native function calls.

Implementations

impl<'r, T> CallContext<'r, T>

pub fn mock<ID: ModuleId>( module_id: ID, location: Location, env: &'r Environment<T> ) -> Self

Creates a mock call context with the specified module ID and call span. The provided Environment is used to extract an OrdArithmetic implementation.

pub fn call_location(&self) -> &LocationInModule

Returns the call location of the currently executing function.

pub fn apply_call_location<U>(&self, value: U) -> Location<U>

Applies the call span to the specified value.

pub fn call_site_error(&self, error: ErrorKind) -> Error

Creates an error spanning the call site.

pub fn check_args_count( &self, args: &[SpannedValue<T>], expected_count: impl Into<LvalueLen> ) -> Result<(), Error>

Checks argument count and returns an error if it doesn’t match.
