Trait JsonSafeFields 

pub trait JsonSafeFields { }

Marker trait proving a type’s u64/i64 fields are protected for JS-safe JSON serialization.

How it works

The #[json_safe_fields] attribute macro auto-implements this trait for annotated types. The #[derive(JsonConvertible)] macro implements it for versioned enums and asserts that all inner variant types also implement it.

Compile errors

If you see the trait `JsonSafeFields` is not satisfied, it means a field type in an annotated struct doesn’t implement this trait. Fix it by one of:

• Struct with u64 fields: add #[cfg_attr(feature = "json-conversion", json_safe_fields)]
• Simple enum/struct without u64: add impl JsonSafeFields for MyType {} below
• BTreeMap<K, u64> field: add #[serde(with = "json_safe_generic_u64_value_map")]
• New type Foo = u64 alias: add it to U64_ALIASES in the proc macro crate

Why u64/i64 don’t implement this trait

A bare u64 is NOT JS-safe. Safety comes from #[serde(with = "json_safe_u64")] applied at the field level. By excluding u64/i64 from this trait, the compiler catches unprotected type aliases (type Foo = u64) and containers (Vec<u64>) at compile time.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
