f# - Compiler can't tell which record type with duplicate fields should be the function parameter type -

-

In my program there are some record types with some field names (each record type means something different). The compiler says that the function parameter matching this record size should be declared as last, even if I declare events in the record with clear field names, and always going through a constant type in each function I am

Is there a proper way to deal with this? I know that I can put a type of annotation on the function, but I think if I am working correctly, then I will not need to fight the compiler with type annotation.

Minimum code problem: 

  type type1 = {x: int} type type2 = {x: int} let's getX t = tx getX {type1.x = 1} | & Gt;

Compiler output: 

  $ fsharpc --nologo test.fs /tmp/typetest/test.fs(7,6): error FS0001: this The expression was expected to be type type 2 but type type1 here

there are some Methods of Nearby:

  1. Type the annotation as you suggested: 

      Let getx (t: type1) = tx < / Code>

  2. Set the getX before the defined type: 

      type1 = {x: int} Type letx t = tx type2 = {x: int}

  3. Do not explicitly specify the type when calling the function: 

      getX {x = 1}

Which of these The little option depends on the exact situation in the 'right' way.

java - Gradle dependencies: compile project by relative path -

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
