Struct test_generation::transitions::Subst

source · [−]

pub struct Subst {
    pub subst: HashMap<usize, SignatureToken>,
}

Expand description

A substitution is a mapping from type formal index to the SignatureToken representing the type instantiation for that index.

Fields

subst: HashMap<usize, SignatureToken>

Implementations

impl Subst

pub fn new() -> Self

pub fn check_and_add(
    &mut self,
    state: &AbstractState,
    stack_sig: SignatureToken,
    instr_sig: SignatureToken
) -> bool

NB that the position of arguments here matters. We can build a substitution if the instr_sig is a type parameter, and the stack_sig is a concrete type. But, if the instruction signature is a concrete type, but the stack signature is a type parameter, they cannot unify and no substitution is created.

pub fn instantiation(self) -> Vec<SignatureToken>ⓘNotable traits for Vec<u8, A>`impl<A> Write for Vec<u8, A> where A: Allocator,`

Return the instantiation from the substitution that has been built.
