Struct MathError 

pub struct MathError {
    pub span: Option<Range<usize>>,
    pub message: String,
}

Why an equation could not be laid out.

Fields

span: Option<Range<usize>>

The offending source, as a byte range on char boundaries, when known.

message: String

Implementations

impl MathError

pub fn char_pos(&self, source: &str) -> Option<usize>

The 1-based character position of the error in source, when known.

Trait Implementations

impl Clone for MathError

fn clone(&self) -> MathError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MathError

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

Formats the value using the given formatter.

impl Display for MathError

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

Formats the value using the given formatter.

impl Eq for MathError

impl Error for MathError

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 MathError

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

Equality operator ==.

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

Inequality operator !=.
