meta inductive level  :
Type

A type universe term. eg max u v. Reflect a C++ level object. The VM replaces it with the C++ implementation.

source
@[instance]
meta def level.​inhabited  :
inhabited level

source
@[instance]
meta constant level.​has_decidable_eq  :
decidable_eq level

source
meta constant level.​lt  :
level → level → bool

source
meta constant level.​lex_lt  :
level → level → bool

source
meta constant level.​fold {α : Type} :
level → α → (level → α → α) → α

source
meta constant level.​normalize  :
level → level

Return the given level expression normal form

source
meta constant level.​eqv  :
level → level → bool

Return tt iff lhs and rhs denote the same level. The check is done by normalization.

source
meta constant level.​occurs  :
level → level → bool

Return tt iff the first level occurs in the second

source
meta constant level.​instantiate  :
level → list (name × level) → level

Replace a parameter named n with l in the first level if the list contains the pair (n, l)

source
meta constant level.​to_format  :
level → options → format

source
meta constant level.​to_string  :
level → string

source

meta def level.​has_to_string  :
has_to_string level

source
@[instance]
meta def level.​has_to_format  :
has_to_format level

source
meta def level.​of_nat  :
ℕ → level

source
meta def level.​has_param  :
