Trouble Composing Schemas with Transformations in Effect Typescript Library

I am having trouble composing some schemas.

For example I have defined a

BooleanFromSwitch

BooleanFromSwitch

, which is a property signature:

optionalToRequired(Literal('on'), Boolean)

optionalToRequired(Literal('on'), Boolean)

, and a

BinaryFromBoolean

BinaryFromBoolean

, which is a transform

transform(NumberFromString, NullOr(Number)

transform(NumberFromString, NullOr(Number)

.

I need to include a

published

published

field in a

Struct

Struct

which transforms a Switch to a Binary and I would rather compose existing schemas, but I understand that I can't simply

compose

compose

the 2.

I also tried to

compose

compose

Struct

Struct

containing that field and then using

extend

extend

to merge it with the rest of the final

Struct

Struct

, but it fails at runtime. The composition also does not have a

fields

fields

field I can spread directly.

Is my only option to define a

BinaryFromSwitch
