Struct catalyst_entities::CodeAllocator

pub struct CodeAllocator { /* private fields */ }

Used for allocating executable memory, serializing compiled code and synchronizing code relocations.

Implementations

impl CodeAllocator

pub fn new() -> Self

Creates a new CodeAllocator. No memory is allocated until the first call to alloc.

pub fn data<'a>(&'a self, code: &Code, finishing: bool) -> CodeGuard<'a>

Gives access to Allocated code. More in CodeGuard docs. This function uses spin lock. If you are holding mutable guard, try to hold it for as short as possible. When finishing is true the code will be frozen after guard is dropped.

pub fn alloc( &mut self, instructions: &[u8], align: Align, thread: u8, finished: bool ) -> Code

Allocates the instructions in the executable memory. The align is the align of allocation. The thread is stored in resulting code. If finished is true, the code is frozen from the start.

Trait Implementations

impl Archive for CodeAllocator

type Archived = ArchivedArchivableCodeAllocator

The archived representation of this type.

type Resolver = ArchivableCodeAllocatorResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived )

Creates the archived version of this value at the given position and writes it to the given output.

impl Default for CodeAllocator

fn default() -> Self

Returns the “default value” for a type.

impl<S: Serializer + ScratchSpace> Serialize<S> for CodeAllocator

fn serialize( &self, serializer: &mut S ) -> Result<Self::Resolver, <S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
