PanicSignatureInfo

cairo_lang_lowering::panic

Struct PanicSignatureInfo 

Source 
pub struct PanicSignatureInfo {
    pub err_variant: ConcreteVariant,
    pub actual_return_ty: TypeId,
    pub always_panic: bool,
    /* private fields */
}

Fields§

§err_variant: ConcreteVariant

The Err() variant.

§actual_return_ty: TypeId

The PanicResult concrete type - the new return type of the function.

§always_panic: bool

Does the function always panic. Note that if it does - the function returned type is always (Panic, Array<felt252>).
