Struct MonoClassField 

pub struct MonoClassField(/* private fields */);

An opaque handle to a Mono runtime object.

Thread safety

This type is intentionally !Send + !Sync. Every thread that reads or writes Mono objects must first be registered with the runtime via crate::MonoThreadGuard::attach. Using a handle on an unregistered thread is undefined behavior — Mono’s garbage collector and internal bookkeeping assume all active threads are known to the runtime.

Handles are therefore bound to the thread on which they were obtained. The compiler enforces this: a handle cannot be moved to another thread without explicit unsafe code.

If you need to transfer a handle across thread boundaries and you can guarantee that both threads are attached to the runtime for the entire duration of use, you can opt in manually on your wrapper type:

struct MyComponent {
    class: mono_rt::MonoClass,
}

// SAFETY: `class` is only accessed while the calling thread holds a
// `MonoThreadGuard`, ensuring it is registered with the Mono runtime.
unsafe impl Send for MyComponent {}
unsafe impl Sync for MyComponent {}

Implementations

impl MonoClassField

pub fn as_ptr(self) -> *mut c_void

pub fn from_ptr(ptr: *mut c_void) -> Option<Self>

pub unsafe fn from_ptr_unchecked(ptr: *mut c_void) -> Self

Safety

ptr must be non-null and valid on a thread attached to the Mono runtime.

impl MonoClassField

pub fn offset(self) -> Result<u32>

Returns the byte offset of this field within its declaring class.

Errors

Returns crate::MonoError::Uninitialized if the Mono API has not been initialized.

pub fn name(self) -> Result<String>

Returns the name of this field as reported by the Mono runtime.

The returned string is copied out of Mono’s metadata and is safe to use beyond the lifetime of the runtime handle.

Errors

Returns crate::MonoError::Uninitialized if the Mono API has not been initialized.

pub fn mono_type(self) -> Result<Option<MonoType>>

Returns the MonoType descriptor for this field.

Errors

Returns crate::MonoError::Uninitialized if the Mono API has not been initialized.

pub unsafe fn static_value( self, vtable: MonoVTable, out: *mut c_void, ) -> Result<()>

Reads the static field value into the out buffer via the given vtable.

Errors

Returns crate::MonoError::Uninitialized if the Mono API has not been initialized.

Safety

out must point to valid memory sized for the field type.
