Trait font_info::FontInfoLoader

pub trait FontInfoLoader {
    // Required method
    fn load_font_info<S, E>(
        &self,
        source: S,
        index: u32
    ) -> Result<FontInfo, Error>
       where S: TryInto<FontAssetSource, Error = E>,
             E: Sync + Send + Into<Error>;
}

An object that can load a FontInfo from a FontAssetSource.

Separate from the implementation to allow easier mocking for tests.

Required Methods

fn load_font_info<S, E>(&self, source: S, index: u32) -> Result<FontInfo, Error>

where S: TryInto<FontAssetSource, Error = E>, E: Sync + Send + Into<Error>,

Load information about a font from the given file source, located at the given index within the file.

S is any type for which a conversion is defined into FT_Open_Args. In practice, this must be either a something that contains an FT_Stream, or a file path.

For simplicity, use [crates::sources::FontAssetSource].
