Struct BridgeCall 

pub struct BridgeCall { /* private fields */ }

Convenience builder for a single FFI call.

Example

#[no_mangle]
pub extern "C" fn my_fn(input: FfiBuffer) -> FfiResult {
    BridgeCall::new(input).run(|buf| {
        // buf is the input, return Result<FfiBuffer, FfiError>
        let val: u32 = unsafe { buf.to_json()? };
        FfiBuffer::from_json(&(val * 2))
    })
}

Implementations

impl BridgeCall

pub fn new(input: FfiBuffer) -> Self

Create a BridgeCall from an input buffer received over FFI.

pub fn run<F>(self, handler: F) -> FfiResult

where F: FnOnce(&FfiBuffer) -> Result<FfiBuffer, FfiError> + UnwindSafe,

Execute handler with the input buffer and return an FfiResult.

The closure is run inside catch_panic, so panics are safely converted to FfiErrorCode::Panic results.

pub fn run_json<I, O, F>(self, handler: F) -> FfiResult

where I: DeserializeOwned + UnwindSafe, O: Serialize, F: FnOnce(I) -> Result<O, FfiError> + UnwindSafe,

Execute handler with a JSON-deserialized input value.

Deserializes I from the input buffer’s JSON content, then calls handler. The output is serialized back to JSON and returned.

pub fn into_buffer(self) -> FfiBuffer

Return the raw input buffer (consumes self).
