An exhaustive list of compiler errors.

Variants

InvalidUTF8(Vec<u8>)

An invalid UTF-8 sequence.

InputFailure(Error)

A failure during the input process.

InvalidChar(char)

A Unicode character not accepted by the Haskell language.

InvalidToken(LexError)

An error during the tokenization process.

IncompleteLexeme(LexemeType)

A lexeme ended prematurely, e.g. EOF in a block comment.

FloatOutOfBound(BigInt)

A float literal is too large (or small) to represent.

Note:

• maximum value for IEEE 754 64-bit double is approximately 1.8e308;
• to prevent loss of precision, maximum value to store in IEEE 754 64-bit double is 2^53;
• Rational with an exponent 4096 takes approximately 13.3KiB to store;
• large float literals may eventually exhaust the usable memory of the compiler;
• Rational is probably not a good representation for large floats;

CharOutOfBound(BigInt)

A character/string literal contains a Unicode character out of bound.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.
