Struct wasmer_vm::VMMemoryDefinition

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

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.

Trait Implementations

impl Clone for VMMemoryDefinition

fn clone(&self) -> VMMemoryDefinition

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VMMemoryDefinition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl MemoryUsage for VMMemoryDefinition

fn size_of_val(&self, tracker: &mut dyn MemoryUsageTracker) -> usize

Returns the size of the referenced value in bytes.

impl Copy for VMMemoryDefinition

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.

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.
