Parsing error kind.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

NonAsciiInput

Input is not in ASCII.

§

Literal(Error)

Error parsing literal.

§

LiteralName

Literal is used where a name is expected, e.g., as a function identifier.

An example of input triggering this error is 1(2, x); 1 is used as the function identifier.

§

Type(Error)

Error parsing type annotation.

§

UnsupportedOp(Op)

Unary or binary operation switched off in the parser features.

§

UnexpectedChar

No rules where expecting this character.

Fields

§context: Option<Context>

Parsing context.

§

UnexpectedTerm

Unexpected expression end.

Fields

§context: Option<Context>

Parsing context.

§

Leftovers

Leftover symbols after parsing.

§

Incomplete

Input is incomplete.

§

UnfinishedComment

Unfinished comment.

§

ChainedComparison

Chained comparison, such as 1 < 2 < 3.

§

Other

Other parsing error.

Fields

§kind: ErrorKind

nom-defined error kind.

§context: Option<Context>

Parsing context.
