Expand description

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.

Implementors

`impl Memory for LinearMemory`[src]

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

Returns the 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.

Returns None if memory can’t be grown by the specified amount of wasm pages.

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

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