Struct DynamicPlugin 

pub struct DynamicPlugin { /* private fields */ }

Owned plugin instance backed by a dynamic library.

Implementations

impl DynamicPlugin

pub unsafe fn from_raw( raw: *mut dyn UdfPlugin, destroy: UdfDestroyFn, lib: Arc<Library>, path: String, ) -> Result<Self, UdfError>

Take ownership of a raw plugin pointer created by udf_create.

Safety

raw must be a non-null pointer returned by the matching udf_create of the same library version, and destroy must be the matching udf_destroy symbol from that library.

Trait Implementations

impl Debug for DynamicPlugin

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for DynamicPlugin

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Send for DynamicPlugin

impl Sync for DynamicPlugin

impl UdfPlugin for DynamicPlugin

fn name(&self) -> &str

Function name used for registration (case-insensitive).

fn description(&self) -> &str

Human readable description.

fn min_arity(&self) -> usize

Minimum number of accepted arguments.

fn max_arity(&self) -> usize
