Struct OptionView 

pub struct OptionView<'a> { /* private fields */ }

Read-only view over an OptionMap borrowed across the FFI.

The plugin contract hands the loader-owned &OptionMap to the plugin for the duration of create; this wrapper gives plugin authors a typed accessor surface without forcing them to construct a HashMap<String, String> themselves.

Implementations

impl<'a> OptionView<'a>

pub fn new(inner: &'a OptionMap) -> Self

Wrap a borrow over an option map. The macro-generated entry point typically reinterprets the incoming *const Options as &OptionMap and hands it here.

pub unsafe fn from_raw_ptr(ptr: *const c_void) -> Option<Self>

Wrap a raw pointer that the loader produced. The pointer must point at a value layout-compatible with OptionMap and remain valid for the borrow. A NULL pointer yields None.

Safety

ptr must either be NULL or point at a value that is layout-compatible with OptionMap and valid for 'a.

pub fn get_str(&self, key: &str) -> Option<&str>

Read a string option. Returns None if the key is absent or the value isn’t a OptionValue::String.

pub fn get_u32(&self, key: &str) -> Option<u32>

Read a u32 option. Returns None if the key is absent or the value isn’t a OptionValue::U32.

pub fn get_map(&self, key: &str) -> Option<OptionView<'_>>

Read a nested map option. Returns None if the key is absent or the value isn’t a OptionValue::Map.

pub fn is_empty(&self) -> bool

True if the map contains no entries.
