## Trait Options
52
+
53
+
The Rust renderer provides sensible default traits when generating the various Rust types you client will use. However, you may wish to configure these traits to better suit your needs. The `traitOptions` attribute is here to help you with that. Let's see the various settings it provides.
54
+
55
+
### Default traits
56
+
57
+
Using the `traitOptions` attribute, you may configure the default traits that will be applied to every Rust type. These default traits can be configured using 4 different attributes:
58
+
59
+
-`baseDefaults`: The default traits to implement for all types.
60
+
-`dataEnumDefaults`: The default traits to implement for all data enum types, in addition to the `baseDefaults` traits. Data enums are enums with at least one non-unit variant — e.g. `pub enum Command { Write(String), Quit }`.
61
+
-`scalarEnumDefaults`: The default traits to implement for all scalar enum types, in addition to the `baseDefaults` traits. Scalar enums are enums with unit variants only — e.g. `pub enum Feedback { Good, Bad }`.
62
+
-`structDefaults`: The default traits to implement for all struct types, in addition to the `baseDefaults` traits.
63
+
64
+
Note that you must provide the fully qualified name of the traits you provide (e.g. `serde::Serialize`). Here are the default values for these attributes:
In addition to configure the default traits, you may also override the traits for specific types. This will completely replace the default traits for the given type. To do so, you may use the `overrides` attribute of the `traitOptions` object.
87
+
88
+
This attribute is a map where the keys are the names of the types you want to override, and the values are the traits you want to apply to these types. Here is an example:
You may also configure which traits should be rendered under a feature flag by using the `featureFlags` attribute. This attribute is a map where the keys are feature flag names and the values are the traits that should be rendered under that feature flag. Here is an example:
Now, if at any point, we encounter a `fruits::Apple` or `fruits::Banana` trait to be rendered (either as default traits or as overridden traits), they will be rendered under the `fruits` feature flag. For instance:
Note that for feature flags to be effective, they must be added to the `Cargo.toml` file of the generated Rust client.
124
+
125
+
### Using the Fully Qualified Name
126
+
127
+
By default, all traits are imported using the provided Fully Qualified Name which means their short name will be used within the `derive` attributes.
128
+
129
+
However, you may want to avoid importing these traits and use the Fully Qualified Name directly in the generated code. To do so, you may use the `useFullyQualifiedName` attribute of the `traitOptions` object by setting it to `true`:
130
+
131
+
```ts
132
+
const traitOptions = {
133
+
useFullyQualifiedName: true,
134
+
};
135
+
```
136
+
137
+
Here is an example of rendered traits with this option set to `true` and `false` (which is the default):
138
+
139
+
```rust
140
+
// With `useFullyQualifiedName` set to `false` (default).
141
+
useserde::Serialize;
142
+
useserde::Deserialize;
143
+
// ...
144
+
#[derive(Serialize, Deserialize)]
145
+
146
+
// With `useFullyQualifiedName` set to `true`.
147
+
#[derive(serde::Serialize, serde::Deserialize)]
148
+
```
149
+
150
+
Note that any trait rendered under a feature flag will always use the Fully Qualified Name in order to ensure we only reference the trait when the feature is enabled.
