§Example

ⓘ
use type_bridge_server::{SchemaSource, PipelineError};
use type_bridge_core_lib::schema::TypeSchema;

struct RemoteSchemaSource { url: String }

impl SchemaSource for RemoteSchemaSource {
    fn load(&self) -> Result<TypeSchema, PipelineError> {
        let content = fetch_schema(&self.url)?;
        TypeSchema::from_typeql(&content)
            .map_err(|e| PipelineError::Schema(e.to_string()))
    }
}
