Type Alias: TokenEncodingId

type TokenEncodingId = TokenEncoding | (string & {});

Defined in: src/lib/classes/tokenizable.ts:93

A recognised token-encoding identifier: one of the closed TokenEncoding built-ins, OR any other string registered via registerTokenEstimator.

Remarks

The (string & {}) half of the union is a widening trick, not a real intersection — string & {} has no members beyond string, so it accepts any string value while TokenEncoding still contributes its literal members to editor autocomplete (a bare string union member would erase that autocomplete entirely, since TypeScript collapses TokenEncoding | string to string). Use this type wherever an API accepts "a built-in encoding, or a registered custom one" — for example Tokenizable.estimateTokens's encoding parameter. APIs that only ever accept the CLOSED built-in set (e.g. a battery's tokenEncoding validation list) should keep using TokenEncoding.
