Struct ExecutionSessionRef

pub struct ExecutionSessionRef<'ee> {
    es: LLVMOrcExecutionSessionRef,
    _marker: PhantomData<&'ee ()>,
}

A JIT execution session reference.

Returned by LLJIT::get_execution_session and MaterializationResponsibilityRef::get_execution_session.

ExecutionSession represents the JIT’d program and provides context for the JIT: It contains the JITDylibs, error reporting mechanisms, and dispatches the materializers.

See the ORCv2 docs.

Fields

es: LLVMOrcExecutionSessionRef

_marker: PhantomData<&'ee ()>

Implementations

impl ExecutionSessionRef<'_>

pub unsafe fn from_inner(es: LLVMOrcExecutionSessionRef) -> Self

Wraps a raw pointer.

pub fn as_inner(&self) -> LLVMOrcExecutionSessionRef

Unwraps the raw pointer.

pub fn intern(&self, name: &CStr) -> SymbolStringPoolEntry

Intern a string in the ExecutionSession’s SymbolStringPool and return a reference to it.

pub fn get_dylib_by_name(&self, name: &CStr) -> Option<JITDylibRef>

Returns the JITDylib with the given name, if any.

pub fn create_bare_jit_dylib(&self, name: &CStr) -> JITDylibRef

Create a “bare” JITDylib.

The client is responsible for ensuring that the JITDylib’s name is unique.

This call does not install any library code or symbols into the newly created JITDylib. The client is responsible for all configuration.

pub fn create_jit_dylib(&self, name: &CStr) -> Result<JITDylibRef, LLVMString>

Create a JITDylib.

The client is responsible for ensuring that the JITDylib’s name is unique.

If a Platform is attached to the ExecutionSession then Platform::setupJITDylib will be called to install standard platform symbols (e.g. standard library interposes). If no Platform is installed then this call is equivalent to Self::create_bare_jit_dylib and will always return success.

pub fn set_default_error_reporter(&self)

Sets the default error reporter to the ExecutionSession.

Uses [tracing::error!] to log the error message.

pub fn set_error_reporter(&self, f: fn(_: &CStr))

Attach a custom error reporter function to the ExecutionSession.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
