Struct move_model::spec_translator::SpecTranslator

pub struct SpecTranslator<'a, 'b, T: ExpGenerator<'a>> { /* private fields */ }

A helper which reduces specification conditions to assume/assert statements.

Implementations

impl<'a, 'b, T: ExpGenerator<'a>> SpecTranslator<'a, 'b, T>

pub fn translate_fun_spec( auto_trace: bool, for_call: bool, builder: &'b mut T, fun_env: &'b FunctionEnv<'a>, type_args: &[Type], param_substitution: Option<&'b [TempIndex]>, ret_locals: &'b [TempIndex] ) -> TranslatedSpec

Translates the specification of function fun_env. This can happen for a call of the function or for its definition (parameter for_call). This will process all the conditions found in the spec block of the function, dealing with references to old(..), and creating respective memory/spec var saves. If for_call is true, abort conditions will be translated for the current state, otherwise they will be treated as in an old. and creating respective memory/spec var saves. It also allows to provide type arguments with which the specifications are instantiated, as well as a substitution for temporaries. The later two parameters are used to instantiate a function specification for a given call context.

pub fn translate_invariants( auto_trace: bool, builder: &'b mut T, invariants: impl Iterator<Item = (&'b GlobalInvariant, Vec<Type>)> ) -> TranslatedSpec

Translates a set of invariants with type instantiations. If there are any references to old(...) they will be rewritten and respective memory/spec var saves will be generated.

pub fn translate_inline_property( builder: &'b mut T, prop: &Exp ) -> (TranslatedSpec, Exp)

Translate one inline property. If there are any references to old(...) they will be rewritten and respective memory/spec var saves will be generated.

pub fn translate_invariants_by_id( auto_trace: bool, builder: &'b mut T, inv_ids: impl Iterator<Item = (GlobalId, Vec<Type>)> ) -> TranslatedSpec
