Enum BuildError 

#[non_exhaustive]
pub enum BuildError {
    Empty,
    EmptyTerm,
    TermTooLong,
    TooManyTerms,
}

Why a trie could not be built.

Variants (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.

Empty

No terms were given.

EmptyTerm

A term was the empty string (for Trie::build_normalized: after normalisation, as for a term made only of combining marks).

TermTooLong

A term is longer than 65535 bytes (for Trie::build_normalized: after normalisation).

TooManyTerms

More than u32::MAX terms were given: term ids and input indices are u32, and u32::MAX itself is reserved for NO_TERM.
