Enum FontConfigError 

pub enum FontConfigError {
    Io {
        path: PathBuf,
        source: Error,
    },
    Json {
        path: PathBuf,
        source: Error,
    },
    UnknownAbbrev {
        path: PathBuf,
        face: &'static str,
        abbrev: String,
    },
    UnsupportedCollectionIndex {
        abbrev: String,
        index: u32,
    },
    RegularRequired,
    Font(FontError),
}

Errors from discovering or resolving a font configuration. Distinct from FontError (which is about a font file failing to load/parse): this type is about the configuration pointing at a bad state in the first place (malformed JSON, a dangling abbrev reference, an unsupported TTC index, …). FontErrors that occur while actually loading a resolved path are wrapped via Font.

Trait Implementations

impl Debug for FontConfigError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FontConfigError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for FontConfigError

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.

impl From<FontError> for FontConfigError

fn from(source: FontError) -> Self

Converts to this type from the input type.
