Struct ClaudeProvider 

pub struct ClaudeProvider { /* private fields */ }

Claude (Anthropic) AI provider adapter

Uses the Anthropic Messages API with tool_use to enforce structured JSON output matching caller-supplied JSON schemas.

Implementations

impl ClaudeProvider

pub fn new(api_key: String) -> Self

Create a new Claude provider with an API key and default settings

Example

use stygian_graph::adapters::ai::claude::ClaudeProvider;

let provider = ClaudeProvider::new("sk-ant-api03-...".to_string());

pub fn with_config(config: ClaudeConfig) -> Self

Create a new Claude provider with custom configuration

Example

use stygian_graph::adapters::ai::claude::{ClaudeProvider, ClaudeConfig};

let config = ClaudeConfig::new("sk-ant-api03-...".to_string())
    .with_model("claude-3-5-sonnet-20241022");
let provider = ClaudeProvider::with_config(config);

Trait Implementations

impl AIProvider for ClaudeProvider

fn extract<'life0, 'async_trait>( &'life0 self, content: String, schema: Value, ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Extract structured data from content using Claude’s tool_use JSON mode

Example

use stygian_graph::adapters::ai::claude::ClaudeProvider;
use stygian_graph::ports::AIProvider;
use serde_json::json;

let provider = ClaudeProvider::new(std::env::var("ANTHROPIC_API_KEY").unwrap_or_default());
let schema = json!({
    "type": "object",
    "properties": {"title": {"type": "string"}},
    "required": ["title"]
});
// let result = provider.extract("<h1>Hello</h1>".to_string(), schema).await;

fn stream_extract<'life0, 'async_trait>( &'life0 self, content: String, schema: Value, ) -> Pin<Box<dyn Future<Output = Result<BoxStream<'static, Result<Value>>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Stream extraction results as they arrive from Claude

Returns partial JSON chunks in SSE stream format.

Example

use stygian_graph::adapters::ai::claude::ClaudeProvider;
use stygian_graph::ports::AIProvider;
use serde_json::json;
use futures::StreamExt;

let provider = ClaudeProvider::new(std::env::var("ANTHROPIC_API_KEY").unwrap_or_default());
let schema = json!({"type": "object"});
// let mut stream = provider.stream_extract("content".to_string(), schema).await.unwrap();
// while let Some(chunk) = stream.next().await { ... }
