Type Alias ClauseDbVar 

pub type ClauseDbVar = DeBruijnVar<TraitClauseId>;

Aliased Type

pub enum ClauseDbVar {
    Bound(DeBruijnId, TraitClauseId),
    Free(TraitClauseId),
}

Variants

Bound(DeBruijnId, TraitClauseId)

A variable attached to the nth binder, counting from the innermost.

Free(TraitClauseId)

A variable not attached to a particular binder. Can be used for various purposes which manipulating types, e.g. as inference variables or placeholders. If --unbind-item-vars is set, we use Free variables to refer to the item binders; Free variables should not otherwise be found in the output of running charon.

fn with_ctx<'a>(&'a self, ctx: &'a C) -> WithCtx<'a, C, Self>

Returns a struct that implements Display. This allows the following:
