pub struct Font<'a> {
    pub header: Header,
    /* private fields */
}

The structure for the font.

Example

   // Stuff
});

Fields

header: Header

The font header for this font.

Implementations

impl<'a> Font<'a>

pub fn display_glyph<T: TryInto<u32>>( &self, char: T, action: impl FnMut(u8, u8, u8), )

Displays a glyph. This will NOT trim the glyph, so you will still get the vertical padding.

Arguments

• char - Pretty self explanitory. A character or integer, that must represent a glyph on the ASCII table.
• action - A closure that takes in 3 values, the bit (always 0 or 1), the x, and the y.

Panics

• If the character can’t be properly converted into a u32.
• If the character can’t be described with 2 bytes or less in UTF-8.

pub fn load(raw: &'a [u8]) -> Self

Loads a font.

Arguments

• raw - The raw bytes for the font file itself.

Panics

• If the file header is incomplete/corrupted in pretty much any way.
• If the magic doesn’t match.
• If the file size doesn’t is bigger than 0x4000 (16384) bytes.
