Enum ParagraphError 

#[non_exhaustive]
pub enum ParagraphError {
    InvalidSize(f32),
    InvalidWidth(f32),
    InvalidSpan(Range<usize>),
    InvalidRange(Range<usize>),
    UnreadableFont,
}

Why a paragraph could not be laid out.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidSize(f32)

A font size outside (0, MAX_FONT_PX], or a line height outside (0, MAX_LINE_HEIGHT].

InvalidWidth(f32)

The maximum width is not a finite, non-negative number.

InvalidSpan(Range<usize>)

A span’s range is reversed, outside the text, or splits a character.

InvalidRange(Range<usize>)

A byte range (such as an input method’s cursor in its preedit text) is reversed, outside its text, or splits a character.

UnreadableFont

The shaper chose a font whose data cannot be read for drawing.

Trait Implementations

impl Clone for ParagraphError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParagraphError

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

Formats the value using the given formatter.

impl Display for ParagraphError

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

Formats the value using the given formatter.

impl Error for ParagraphError

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 PartialEq for ParagraphError

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

Equality operator ==.

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

Inequality operator !=.
