pub struct Env { /* private fields */ }

Implementations

source

impl Env

source

pub fn memory_ref(&self) -> Option<&Memory>

Get access to the underlying data.

If WasmerEnv::finish has been called, this function will never return None unless the underlying data has been mutated manually.

source

pub unsafe fn memory_ref_unchecked(&self) -> &Memory

Gets the item without checking if it’s been initialized.

Safety

WasmerEnv::finish must have been called on this function or this type manually initialized.

source

pub fn allocate_ref(&self) -> Option<&Function>

Get access to the underlying data.

If WasmerEnv::finish has been called, this function will never return None unless the underlying data has been mutated manually.

source

pub unsafe fn allocate_ref_unchecked(&self) -> &Function

Gets the item without checking if it’s been initialized.

Safety

WasmerEnv::finish must have been called on this function or this type manually initialized.

source

pub fn deallocate_ref(&self) -> Option<&Function>

Get access to the underlying data.

If WasmerEnv::finish has been called, this function will never return None unless the underlying data has been mutated manually.

source

pub unsafe fn deallocate_ref_unchecked(&self) -> &Function

Gets the item without checking if it’s been initialized.

Safety

WasmerEnv::finish must have been called on this function or this type manually initialized.
