Macros

call_result_cb

ffi_error

Converts a result into a pair of (error_code: i32, description: CString) to be used in FfiResult

ffi_error_code

ffi_result

Converts a result into a pair of (error_code: i32, description: CString) to be used in FfiResult

ffi_result_code

try_cb

Structs

FfiResult

FFI result wrapper.

OpaqueCtx

Type that holds opaque user data handed into FFI functions.

Constants

FFI_RESULT_OK

Constant value to be used for OK result.

Traits

ErrorCode

Trait for types that can be converted to integer error code.

ReprC

Trait to convert between FFI and Rust representations of types

SafePtr

Provides FFI-safe pointers, as opposed to raw as_ptr() in Vec and String which can return values such as 0x01 that can cause segmentation faults with the automatic pointer dereferencing on the front-end side (e.g. in Node.js).

Functions

base64_decode

Decode base64 encoded data.

base64_encode

Encode the data using base64 encoding.

catch_unwind_cb

Catch panics. On error call the callback.

catch_unwind_result

Catches panics and returns the result.

vec_clone_from_raw_parts^⚠

Converts a pointer and lengths to Vec by cloning the contents.

vec_into_raw_parts

Converts a Vec to (pointer, size, capacity).
