[−][src]Enum rusttype::SharedBytes
SharedBytes
handles the lifetime of font data used in RustType. The data
is either a shared reference to externally owned data, or managed by
reference counting. SharedBytes
can be conveniently used with From
and
Into
, and dereferences to the contained bytes.
Lifetime
The lifetime reflects the font data lifetime. SharedBytes<'static>
covers
most cases ie both dynamically loaded owned data and for referenced compile
time font data.
