Trait StringFormatting 

pub trait StringFormatting: Sealed {
    // Required method
    unsafe fn push_vfstring_internal<'a, A>(
        &self,
        format: &str,
        args: A,
    ) -> VmErrorResult<LuaString>
       where A: AsMut<[Arg<'a>]>;

    // Provided method
    unsafe fn push_fstring_internal<'a, A>(
        &self,
        format: &str,
        args: A,
    ) -> VmErrorResult<LuaString>
       where A: AsMut<[Arg<'a>]> { ... }
}

Unstable VM string-formatting capability.

Safety

The thread must be live, format arguments must remain valid for the call, and the caller must account for stack growth, allocation, errors, and GC.

Required Methods

unsafe fn push_vfstring_internal<'a, A>( &self, format: &str, args: A, ) -> VmErrorResult<LuaString>

where A: AsMut<[Arg<'a>]>,

luaO_pushvfstring

Provided Methods

unsafe fn push_fstring_internal<'a, A>( &self, format: &str, args: A, ) -> VmErrorResult<LuaString>

where A: AsMut<[Arg<'a>]>,

luaO_pushfstring

Dyn Compatibility

This trait is not dyn compatible.

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