Source 
pub struct LedFont { /* private fields */ }
Expand description

The Rust handle for LedFont.

Implementations§

Source§

impl LedFont

Source

pub fn new(bdf_file: &Path) -> Result<Self, &'static str>

Creates a new LedFont instance with the given bdf filepath, if it exists.

§Errors
  • If the given bdf_file path fails to convert to a string. This can occur when there is a null character mid way in the string.
  • If the C++ library returns us a null pointer when loading the font.
