Trait TaskMemoryAccessor 

Source 
pub trait TaskMemoryAccessor: MemoryAccessor {
    // Required methods
    fn maximum_valid_address(&self) -> Option<UserAddress>;
    fn ensure_buffers_mapped_in_user_vmar(
        &self,
        buffers: &[UserBuffer],
        access: MappingAccess,
    ) -> Result<(), Errno>;
}

Required Methods§

Source

fn maximum_valid_address(&self) -> Option<UserAddress>

Returns the maximum valid address for this memory accessor.

Source

fn ensure_buffers_mapped_in_user_vmar( &self, buffers: &[UserBuffer], access: MappingAccess, ) -> Result<(), Errno>

Ensures that any mappings in buffers are mapped in the user VMAR with the permissions needed for access.

In older versions of Rust, dyn compatibility was called "object safety".
