Enum MathError 

pub enum MathError {
    UnbalancedDelim {
        delim: AnyDelim,
        range: Range<usize>,
    },
    UnbalancedEnv {
        name: String,
        range: Range<usize>,
    },
    UnbalancedBraces {
        offset: usize,
        region: Range<usize>,
    },
}

An unrecoverable shape the recogniser saw. The scanner never panics; it accumulates these and keeps scanning the rest of the document.

Variants

UnbalancedDelim

\[, \(, $$, or $ with no matching close.

Fields

delim: AnyDelim

range: Range<usize>

Byte range of the opening delimiter token.

UnbalancedEnv

\begin{name} with no matching \end{name} at the same depth.

Fields

name: String

range: Range<usize>

Byte range covering \begin{name} itself.

UnbalancedBraces

{ and } inside a recognised math body do not balance. The region still scans because markers are balanced, but body normalisation is skipped.

Fields

offset: usize

Byte offset (absolute, into the source) of the offending brace — either an unmatched } or the start of the body when the document ends mid-group.

region: Range<usize>

Byte range of the math region whose body failed validation.

Trait Implementations
