Struct FunctionsClient 

pub struct FunctionsClient { /* private fields */ }

HTTP client for Supabase Edge Functions.

Communicates with Edge Functions at /functions/v1/{function_name}.

Example

use supabase_client_functions::{FunctionsClient, InvokeOptions};
use serde_json::json;

let client = FunctionsClient::new("https://your-project.supabase.co", "your-anon-key")?;
let response = client.invoke("hello", InvokeOptions::new()
    .body(json!({"name": "World"}))
).await?;
let data: serde_json::Value = response.json()?;

Implementations

impl FunctionsClient

pub fn new(supabase_url: &str, api_key: &str) -> Result<Self, FunctionsError>

Create a new Edge Functions client.

supabase_url is the project URL (e.g., https://your-project.supabase.co). api_key is the Supabase anon or service_role key.

pub fn base_url(&self) -> &Url

Get the base URL for the functions endpoint.

pub fn api_key(&self) -> &str

Get the API key used by this client.

pub fn set_auth(&self, token: &str)

Update the default auth token for function invocations.

Subsequent invocations will use Bearer <token> unless overridden per-request.

Mirrors supabase.functions.setAuth(token).

pub async fn invoke( &self, function_name: &str, options: InvokeOptions, ) -> Result<FunctionResponse, FunctionsError>

Invoke an Edge Function.

Arguments

• function_name - The name of the deployed function.
• options - Invocation options (body, method, headers, region, etc.).

Errors

• FunctionsError::RelayError if Supabase infrastructure returned an error (x-relay-error: true).
• FunctionsError::HttpError if the function returned a non-2xx status.
• FunctionsError::Http on network failure.
