Types

RpcError

pub type RpcError {
  RpcTimeout
  RpcBadRpc(String)
  RpcFailed(String)
  DecodeFailed(codec.DecodeError)
  NotBinary(String)
}

Constructors

```
RpcTimeout
```
The RPC call timed out.
```
RpcBadRpc(String)
```
The RPC returned a badrpc error.
```
RpcFailed(String)
```
The RPC failed for another reason.
```
DecodeFailed(codec.DecodeError)
```
The result could not be decoded.
```
NotBinary(String)
```
The result was not a binary (for typed RPC).

Values

call

</>

pub fn call(
  node: String,
  module: String,
  function: String,
  args: List(dynamic.Dynamic),
) -> Result(dynamic.Dynamic, RpcError)

Perform a remote procedure call on a node. Calls module:function(args) on the given node.

@deprecated Use call_typed or call_typed_with_timeout with codecs for type-safe RPC. This function bypasses all type checking and encoding validation.

call_typed

</>

pub fn call_typed(
  node: String,
  module: String,
  function: String,
  args: List(dynamic.Dynamic),
  decoder: fn(BitArray) -> Result(a, codec.DecodeError),
  expected_tag: String,
  expected_version: Int,
) -> Result(a, RpcError)

Perform a typed remote procedure call on a node. The remote function must return envelope-wrapped binary data. The result is decoded using the provided Decoder with tag and version validation.

Uses a default timeout of 5000ms.

call_typed_with_timeout

</>

pub fn call_typed_with_timeout(
  node: String,
  module: String,
  function: String,
  args: List(dynamic.Dynamic),
  decoder: fn(BitArray) -> Result(a, codec.DecodeError),
  expected_tag: String,
  expected_version: Int,
  timeout_ms: Int,
) -> Result(a, RpcError)

Perform a typed remote procedure call with an explicit timeout. The remote function must return envelope-wrapped binary data. The result is decoded using the provided Decoder with tag and version validation.

call_with_timeout

</>

pub fn call_with_timeout(
  node: String,
  module: String,
  function: String,
  args: List(dynamic.Dynamic),
  timeout_ms: Int,
) -> Result(dynamic.Dynamic, RpcError)

Uses a default timeout of 5000ms Call with an explicit timeout in milliseconds

@deprecated Use call_typed_with_timeout with codecs for type-safe RPC. This function bypasses all type checking and encoding validation.
