typed.clj.malli — org.typedclojure/typed.clj.malli 1.0.18

Public API for typed ops in malli.core.

In general these operations:

• are macros instead of functions
• take Typed Clojure types instead of malli schemas
• helps the type checker infer their results

-instrument clj macro

(-instrument tmap & args)

=> clj macro

(=> name t)

defparser clj macro

(defparser name t)

Def parser for Typed Clojure type t. Type checker infers the type of the return value when used.

eg., (defparser AnyInteger-parser t/AnyInteger) (AnyInteger-parser 1) ;=> 1 (AnyInteger-parser nil) ;=> :malli.core/invalid

defunparser clj macro

(defunparser name t)

defvalidator clj macro

(defvalidator name t)

Def validator called name for type t. Type checker infers as a predicate on t.

eg., (defvalidator AnyInteger? t/AnyInteger) (AnyInteger? 1) => true (AnyInteger? nil) => false

explain clj macro

(explain t v)

Explain validation failure of v conforming to type t. Type checker infers as a predicate on "not t".

(explain t/AnyInteger 1) => nil (explain t/AnyInteger nil) => {:schema :int, :value nil, :errors ({:path [], :in [], :schema :int, :value nil, :type nil, :message nil})}

parse clj macro

(parse t v)

Parse value v as type t. Type checker infers the shape of return value.

eg., (parse t/AnyInteger 1) ;=> 1 (parse t/AnyInteger nil) ;=> :malli.core/invalid (parse (t/U ^{::name :int} t/AnyInteger ^{::name :bool} t/Bool) 1) ;=> [:int 1] (parse (t/U ^{::name :int} t/AnyInteger ^{::name :bool} t/Bool) true) ;=> [:bool true]

parser clj macro

(parser t)

Create parser for Typed Clojure type t. Type checker infers the type of the return value when used.

eg., ((parser t/AnyInteger) 1) ;=> 1 ((parser t/AnyInteger) nil) ;=> :malli.core/invalid ((parser (t/U ^{::name :int} t/AnyInteger ^{::name :bool} t/Bool)) 1) ;=> [:int 1] ((parser (t/U ^{::name :int} t/AnyInteger ^{::name :bool} t/Bool)) true) ;=> [:bool true]

unparse clj macro

(unparse t v)

unparser clj macro

(unparser t)

validate clj macro

(validate t v)

Validate v as type t. Type checker infers as a predicate on t.

eg., (validate t/AnyInteger 1) => true (validate t/AnyInteger nil) => false

validator clj macro

(validator t)

Create validator for type t. Type checker infers as a predicate on t.

eg., ((validator t/AnyInteger) 1) => true ((validator t/AnyInteger) nil) => false
