@stanhangzhou Rust representation of schema you've described in original question would look something like:
\n#[graphql_interface]\ntrait ImageData {\n fn src(&self) -> String;\n fn content_type(&self) -> Option<String>,\n}\n\n#[graphql_interface]\ntrait CollectionVolume {\n fn change_24h(&self) -> Option<i32>;\n}\n\n#[graphql_interface]\ntrait UserAvatarOmit {\n fn id(&self) -> String;\n fn token_id(&self) -> String;\n fn image(&self) -> ImageDataValue;\n}\n\n#[graphql_interface]\ntrait UserAvatarOmit {\n fn address(&self) -> String;\n fn is_verified(&self) -> bool;\n fn name(&self) -> String;\n fn avatar(&self) -> Option<UserAvatarOmitValue>;\n}\n\n#[graphql_interface]\ntrait CollectionBase {\n fn name(&self) -> String;\n fn logo(&self) -> Option<ImageDataValue>;\n}interface field as interface inherit to maping not implement error #1093

Hi, I had a schema.graphql, But i can't map it to juniper rust code correct! My confused If graphql's interface must map to rust trait? and i finally used box as a field. and @ilslv told me representd interface ImageData map to rust enum? i do not know how to map it. @ my schema.graphql code scalar BigInt
# Long is a 64 bit unsigned integer.
scalar Long
interface ImageData {
src: String!
contentType: String
}
interface CollectionVolume {
change24h: Int
}
interface UserAvatarOmit {
id: String!
tokenId: String!
image: ImageData!
}
interface CollectionOwner {
address: String!
isVerified: Boolean!
name: String!
avatar: UserAvatarOmit
}
interface CollectionBase {
name: String!
logo: ImageData
}
"The root query object of the schema"
type QueryRoot {
collections() : [Collection]
}
type Collection implements CollectionBase {
"collectionbase attr"
name: String!
logo: ImageData
"type collection attr"
owner: CollectionOwner!
}
schema {
query: QueryRoot

@ilslv I now understand i need retyped imageData to rust enum but I still can't compiler correct , pls help when you are free,thanks. #![allow(missing_docs)]

@stanhangzhou Rust representation of schema you've described in original question would look something like: #[graphql_interface]
trait ImageData {
fn src(&self) -> String;
fn content_type(&self) -> Option<String>,
}
#[graphql_interface]
trait CollectionVolume {
fn change_24h(&self) -> Option<i32>;
}
#[graphql_interface]
trait UserAvatarOmit {
fn id(&self) -> String;
fn token_id(&self) -> String;
fn image(&self) -> ImageDataValue;
}
#[graphql_interface]
trait UserAvatarOmit {
fn address(&self) -> String;
fn is_verified(&self) -> bool;
fn name(&self) -> String;
fn avatar(&self) -> Option<UserAvatarOmitValue>;
}
#[graphql_interface]
trait CollectionBase {
fn name(&self) -> String;
fn logo(&self) -> Option<ImageDataValue>;
