Enum Error 

pub enum Error {
    Parse(ParseError),
    Font(FontError),
    Unsupported {
        what: String,
    },
    Malformed {
        what: String,
    },
    InvalidOption {
        what: String,
    },
}

Crate-level error.

Unsupported input is never rendered. Error::Parse wraps tokenizer/parser failures; Error::Font wraps face/glyph failures; Error::Unsupported is a construct or feature out of scope; Error::Malformed is a bad value that parsed as the wrong shape; Error::InvalidOption is a render option out of range.

Variants

Parse(ParseError)

Tokenizer or parser rejected the input.

Font(FontError)

Font bytes or a requested glyph could not be used.

Unsupported

A feature listed as out of scope, or not yet implemented.

Callers must treat this as failure. The renderer does not invent output.

Fields

what: String

Human-readable name of the missing feature or construct.

Malformed

Syntactically invalid value (for example a color spec with the wrong number of components). Distinct from Self::Unsupported.

Fields

what: String

Human-readable description of what was malformed.

InvalidOption

A render option is out of range (for example PNG DPI of 0 or above 2400).

Fields

what: String

Human-readable name of the invalid option.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 Error

fn from(e: FontError) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(e: ParseError) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
