Enum LiteralReadCause 

pub enum LiteralReadCause {
    NotAKnownForm,
    NotReadable,
}

Why one literal spelling could not be read into the value it names.

Neither row is the caller’s mistake: every spelling that reaches this road was already lexed by a compiler, so a refusal is this crate saying it does not read what the compiler admitted.

Variants

NotAKnownForm

The spelling opens with no literal form this grammar has a row for.

NotReadable

The form is one this grammar reads, and its body carries material this grammar could not read the value of.
