Implementations§
source§impl RootModuleError
impl RootModuleError
sourcepub fn reallocate(&mut self)
pub fn reallocate(&mut self)
Reallocates the error using the current global allocator, to ensure that there is no pointer into the dynamic library.
sourcepub fn into_library_error<M: RootModule>(self) -> LibraryError
pub fn into_library_error<M: RootModule>(self) -> LibraryError
Converts this RootModuleError
into a LibraryError
,
with metadata about the module that failed to load.
