Struct opendal::services::Ipfs

pub struct Ipfs { /* private fields */ }

IPFS file system support based on IPFS HTTP Gateway.

Capabilities

This service can be used to:

• read
• write
• list
• scan
• presign
• blocking

Configuration

• root: Set the work directory for backend
• endpoint: Customizable endpoint setting

You can refer to IpfsBuilder’s docs for more information

Example

Via Builder

use anyhow::Result;
use opendal::services::Ipfs;
use opendal::Object;
use opendal::Operator;

#[tokio::main]
async fn main() -> Result<()> {
    // create backend builder
    let mut builder = Ipfs::default();

    // set the endpoint for OpenDAL
    builder.endpoint("https://ipfs.io");
    // set the root for OpenDAL
    builder.root("/ipfs/QmPpCt1aYGb9JWJRmXRUnmJtVgeFFTJGzWFYEEX7bo9zGJ");

    let op: Operator = Operator::new(builder)?.finish();

    // Create an object handle to start operation on object.
    let _: Object = op.object("test_file");

    Ok(())
}

Implementations

impl IpfsBuilder

pub fn root(&mut self, root: &str) -> &mut Self

Set root of ipfs backend.

Root must be a valid ipfs address like the following:

• /ipfs/QmPpCt1aYGb9JWJRmXRUnmJtVgeFFTJGzWFYEEX7bo9zGJ/ (IPFS with CID v0)
• /ipfs/bafybeibozpulxtpv5nhfa2ue3dcjx23ndh3gwr5vwllk7ptoyfwnfjjr4q/ (IPFS with CID v1)
• /ipns/opendal.databend.rs/ (IPNS)

pub fn endpoint(&mut self, endpoint: &str) -> &mut Self

Set endpoint if ipfs backend.

Endpoint must be a valid ipfs gateway which passed the IPFS Gateway Checker

pub fn http_client(&mut self, client: HttpClient) -> &mut Self

Specify the http client that used by this service.
