CustomSection: CustomSectionLike<'module> + 'module,
Available on crate features std or core only.
pub fn allocate<'module, 'memory, FunctionBody, CustomSection>(
&'memory mut self,
functions: &'memory [&'module FunctionBody],
executable_sections: &'memory [&'module CustomSection],
data_sections: &'memory [&'module CustomSection],
) -> Result<(Vec<&'memory mut [VMFunctionBody]>, Vec<&'memory mut [u8]>, Vec<&'memory mut [u8]>), String>where
FunctionBody: FunctionBodyLike<'module> + 'module,
CustomSection: CustomSectionLike<'module> + 'module,
std or core only.Allocate a single contiguous block of memory at a fixed virtual address for the functions and custom sections, and copy the data in place.
Sourcepub fn publish(&mut self)
Available on crate features std or core only.
pub fn publish(&mut self)
std or core only.Apply the page permissions.
Sourcepub fn register_frame_info(&mut self, frame_info: GlobalFrameInfoRegistration)
Available on crate features std or core only.
pub fn register_frame_info(&mut self, frame_info: GlobalFrameInfoRegistration)
std or core only.Register the frame info, so it’s free when the mememory gets freed
