# Struct rustc_infer::traits::solve::inspect::State

source ·

    pub struct State<'tcx, T> {
        pub var_values: CanonicalVarValues<'tcx>,
        pub data: T,
    }

Expand description

Some `data` together with information about how they relate to the input of the canonical query.

This is only ever used as CanonicalState. Any type information in proof trees used mechanically has to be canonicalized as we otherwise leak inference variables from a nested `InferCtxt`.

The type returned in the event of a conversion error.
source§

#### fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.

## Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
