Class ContractLogIndexFilter

Predicate filter on the index query parameter of the two contract-log list endpoints — /api/v1/contracts/results/logs and /api/v1/contracts/{contractIdOrAddress}/results/logs. Narrows results to contract-log entries at a specific block-local position (or to a comparison range thereof). Construct via one of the static factories — the ctor is private so the operator is always explicit at the call site.

Syntax
public sealed class ContractLogIndexFilter : IMirrorFilter, IMirrorQueryParameter
Remarks

Unlike the sibling ContractActionIndexFilter — which shares the same index wire name on the contract-actions endpoint — the log endpoints accept only five operators on the wire: equality (default), gt:, gte:, lt:, and lte:. The schema regex ^((eq|gt|gte|lt|lte):)?\d{1,10}$ explicitly excludes ne:, so no NotIs factory is exposed.

The mirror-node spec also requires a TimestampFilter to be present in the same request whenever this filter appears — the server 400s otherwise. The SDK does not enforce this client side; pass both filters together.

This filter is deliberately distinct from ContractActionIndexFilter: the two endpoints share the index wire name but differ in semantic scope (action-index vs. log-index) and in operator palette (actions accept ne, logs do not).
