Enum FontError 

pub enum FontError {
    NoFacesFound,
}

Types named in TextContext’s own public signatures — register_fonts() -> Result<Vec<RegisteredFamily>, FontError> and shape_cache_stats() -> ShapeCacheStats. Without these an app could call the methods but never name what they return. Errors from TextContext::register_fonts.

Variants

NoFacesFound

The supplied bytes contained no parseable font faces (invalid, empty, or unrecognized data).

impl Eq for FontError

impl Error for FontError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
