begin

Called by dvui during dvui.Window.begin, so prior to any dvui rendering. Use to setup anything needed for this frame. The arena arg is cleared before dvui.Window.begin is called next, useful for any temporary allocations needed only for this frame.

Parameters

self:Backend: Backend
arena:std.mem.Allocator: std.mem.Allocator

Implementation

pub fn begin(self: Backend, arena: std.mem.Allocator) GenericError!void {
    try self.impl.begin(arena);
    if (dvui.render_backend.kind != .default) try self.render_impl.begin(arena);
}
