#[repr(C)]
pub struct VMMemoryDefinition { pub base: *mut u8, pub current_length: usize, }
Expand description

The fields compiled code needs to access to utilize a WebAssembly linear memory defined within the instance, namely the start address and the size in bytes.

Fields§

§base: *mut u8

The start address which is always valid, even if the memory grows.

§current_length: usize

The current logical size of this linear memory in bytes.

impl Copy for VMMemoryDefinition

source§

impl Send for VMMemoryDefinition

Safety

This data is safe to share between threads because it’s plain data that is the user’s responsibility to synchronize.

source§

impl Sync for VMMemoryDefinition

Safety

This data is safe to share between threads because it’s plain data that is the user’s responsibility to synchronize. And it’s Copy so there’s really no difference between passing it by reference or by value as far as correctness in a multi-threaded context is concerned.
