Struct ckb_std::dynamic_loading::CKBDLContext

#[repr(C, align(4096))]
pub struct CKBDLContext<T>(/* private fields */);

Available on crate feature ckb-types only.

Dynamic loading context T represent a buffer type, for example: [u8; 64 * 1024], the size of T must aligned with PAGE_SIZE 4096.

Implementations

impl<T> CKBDLContext<T>

pub unsafe fn new() -> Self

👎Deprecated since 0.7.3: Please use the dynamic_loading_c_impl instead

Unsafe

Undefined behavior will happen if the type T is not a [u8; length]

Create instance of dynamic loading context

pub fn load<'a>( &'a mut self, dep_cell_data_hash: &[u8] ) -> Result<Library, Error>

👎Deprecated since 0.7.3: Please use the dynamic_loading_c_impl instead

Load a shared library from dep cells See module level documentation for details

pub fn load_with_offset<'a>( &'a mut self, dep_cell_data_hash: &[u8], offset: usize, size: usize ) -> Result<Library, Error>

👎Deprecated since 0.7.3: Please use the dynamic_loading_c_impl instead

Load a shared library from dep cells to specified buffer offset. See module level documentation for details

This function is used for loading multiple libraries.

Example

let mut context = CKBDLContext::<[u8; 64 * 1024]>::new();
let mut size = size_of_val(&context);
let mut offset = 0;

let lib1 = context.load(&CODE_HASH_LIB_1).expect("load shared lib");
size -= lib1.consumed_size()
offset += lib1.consumed_size()

let lib2 = context.load_with_offset(&CODE_HASH_LIB_2, offset, size).expect("load shared lib");
size -= lib2.consumed_size()
offset += lib2.consumed_size()

let lib3 = context.load_with_offset(&CODE_HASH_LIB_3, offset, size).expect("load shared lib");
