Why does this not compile? If I inline the get_display function (see comments) it works
use esp_idf_hal::{
gpio::{InputPin, OutputPin},
i2c::{self, I2cDriver},
};
use shared_bus::{BusManager, I2cProxy, NullMutex};
use ssd1306::{
mode::BufferedGraphicsMode, prelude::I2CInterface, size::DisplaySize128x64, Ssd1306,
};
type SharedBus<'a> = BusManager<NullMutex<I2cDriver<'a>>>;
