Struct CodeMemory

Source
pub struct CodeMemory { /* private fields */ }
Expand description

Mappings to regions of memory storing the executable JIT code.

Implementations§

Source§

impl CodeMemory

Source

pub fn resize(self, size: usize) -> Result<Self>

Ensure this CodeMemory is at least of the requested size.

This will invalidate any data previously written into the mapping if the mapping needs to be resized.

Source

pub unsafe fn writer(&mut self) -> CodeMemoryWriter<'_>

Write to this code memory from the beginning of the mapping.

§Safety

At the time this method is called, there should remain no dangling readable/executable references to this CodeMemory, for the original code memory that those references point to are invalidated as soon as this method is invoked.

Source

pub unsafe fn publish(&mut self) -> Result<(), CompileError>

Publish the specified number of bytes as executable code.

§Safety

Calling this requires that no mutable references to the code memory remain.

Source

pub unsafe fn executable_address(&self, offset: usize) -> *const u8

Remap the offset into an absolute address within a read-execute mapping.

Offset must not exceed isize::MAX.

Source

pub unsafe fn writable_address(&self, offset: usize) -> *mut u8

Remap the offset into an absolute address within a read-write mapping.

Offset must not exceed isize::MAX.
