# Hide content in introspection
|
||
|
|
|
||
|
|
By default, all types and fields are visible in introspection. But maybe you want to hide some content according to different users to avoid unnecessary misunderstandings. You can add the `visible` attribute to the type or field to do it.
|
||
|
|
|
||
|
|
```rust
|
||
|
|
use async_graphql::*;
|
||
|
|
|
||
|
|
#[derive(SimpleObject)]
|
||
|
|
struct MyObj {
|
||
|
|
// This field will be visible in introspection.
|
||
|
|
a: i32,
|
||
|
|
|
||
|
|
// This field is always hidden in introspection.
|
||
|
|
#[graphql(visible = false)]
|
||
|
|
b: i32,
|
||
|
|
|
||
|
|
// This field calls the `is_admin` function, which
|
||
|
|
// is visible if the return value is `true`.
|
||
|
|
#[graphql(visible = "is_admin")]
|
||
|
|
c: i32,
|
||
|
|
}
|
||
|
|
|
||
|
|
#[derive(Enum)]
|
||
|
|
enum MyEnum {
|
||
|
|
// This item will be visible in introspection.
|
||
|
|
A,
|
||
|
|
|
||
|
|
// This item is always hidden in introspection.
|
||
|
|
#[graphql(visible = false)]
|
||
|
|
B,
|
||
|
|
|
||
|
|
// This item calls the `is_admin` function, which
|
||
|
|
// is visible if the return value is `true`.
|
||
|
|
#[graphql(visible = "is_admin")]
|
||
|
|
C,
|
||
|
|
}
|
||
|
|
|
||
|
|
struct IsAdmin(bool);
|
||
|
|
|
||
|
|
fn is_admin(ctx: &Context<'_>) -> bool {
|
||
|
|
ctx.data_unchecked::<IsAdmin>().0
|
||
|
|
}
|
||
|
|
|
||
|
|
```
