Struct mun_abi::TypeLut

#[repr(C)]
pub struct TypeLut<'a> {
    pub num_entries: u32,
    /* private fields */
}

Represents a lookup table for type information. This is used for runtime linking.

Type IDs and handles are stored separately for cache efficiency.

Fields

num_entries: u32

Number of types

Implementations

impl<'a> TypeLut<'a>

pub fn iter(&self) -> impl Iterator<Item = (&TypeId<'_>, &*const c_void, &str)>

Returns an iterator over pairs of type IDs and type handles.

pub fn iter_mut(
    &mut self
) -> impl Iterator<Item = (&TypeId<'_>, &mut *const c_void, &str)>

Returns an iterator over pairs of type IDs and mutable type handles.

pub fn type_handles_mut(&mut self) -> &mut [*const c_void]

Returns mutable type handles.

pub fn type_ids(&self) -> &[TypeId<'a>]

Returns type IDs.

pub unsafe fn get_type_handle_unchecked(&self, idx: u32) -> *const c_void

Returns a type handle, without doing bounds checking.

This is generally not recommended, use with caution! Calling this method with an out-of-bounds index is undefined behavior even if the resulting reference is not used. For a safe alternative see get_ptr.

Safety

The idx is not bounds checked and should therefor be used with care.

pub fn get_type_handle(&self, idx: u32) -> Option<*const c_void>

Returns a type handle at the given index, or None if out of bounds.

pub unsafe fn get_type_handle_unchecked_mut(
    &mut self,
    idx: u32
) -> &mut *const c_void

Returns a mutable reference to a type handle, without doing bounds checking.

This is generally not recommended, use with caution! Calling this method with an out-of-bounds index is undefined behavior even if the resulting reference is not used. For a safe alternative see get_ptr_mut.

Safety

The idx is not bounds checked and should therefor be used with care.

pub fn get_type_handle_mut(&mut self, idx: u32) -> Option<&mut *const c_void>

Returns a mutable reference to a type handle at the given index, or None if out of bounds.

pub fn type_names(&self) -> impl Iterator<Item = &str>

Returns type names.
