Trait wasmer_vm::Memory[−][src]

pub trait Memory: Debug + Send + Sync {
    fn ty(&self) -> &MemoryType;
    fn style(&self) -> &MemoryStyle;
    fn size(&self) -> Pages;
    fn grow(&self, delta: Pages) -> Result<Pages, MemoryError>;
    fn vmmemory(&self) -> NonNull<VMMemoryDefinition>;
}

Trait for implementing Wasm Memory used by Wasmer.

Required methods

`fn ty(&self) -> &MemoryType`[src]

Returns the memory type for this memory.

`fn style(&self) -> &MemoryStyle`[src]

Returns the memory style for this memory.

`fn size(&self) -> Pages`[src]

Returns the number of allocated wasm pages.

`fn grow(&self, delta: Pages) -> Result<Pages, MemoryError>`[src]

Grow memory by the specified amount of wasm pages.

`fn vmmemory(&self) -> NonNull<VMMemoryDefinition>`[src]

Return a VMMemoryDefinition for exposing the memory to compiled wasm code.

The pointer returned in VMMemoryDefinition must be valid for the lifetime of this memory.
