Module `Make.Syntax`Source

Applicative syntax

Sourceval (let+) : 'a t -> ('a -> 'b) -> 'b t

Syntax for map. Use this to process the result of a term without using any special effects.

Sourceval (and+) : 'a t -> 'b t -> ('a * 'b) t

Syntax for pair. Use this to depend on multiple terms.

Monadic syntax

Sourceval (let*) : 'a t -> ('a -> 'b t) -> 'b t

Monadic bind. Use this if the next part of your pipeline can only be determined at runtime by looking at the concrete value. Static analysis cannot predict what this will do until the input is ready.

Sourceval (let>) : 'a t -> ('a -> 'b primitive) -> description -> 'b t

let> is used to define a component. e.g.:

  component "my-op" |>
    let> x = fetch uri in
    ...

Sourceval (let**) : 'a t -> ('a -> 'b t) -> description -> 'b t

Like let*, but allows you to name the operation. e.g.:

  component "my-op" |>
    let** x = fetch uri in
    ...

Sourceval (and*) : 'a t -> 'b t -> ('a * 'b) t

Syntax for pair. Use this to depend on multiple terms. Note: this is the same as and+.

Sourceval (and>) : 'a t -> 'b t -> ('a * 'b) t
