Enum FilterClass 

pub enum FilterClass {
    Hard,
    Soft {
        min_remaining: usize,
    },
}

How aggressive a filter is allowed to be when shrinking the candidate set.

Variants

Hard

The filter may filter to zero. If it does, the pipeline surfaces fuel_ir::Error::FilterRejected — the user asked for something the binding-table can’t deliver and we surface it rather than silently substituting a non-admissible alternative.

Use for filters that encode a user-requested correctness floor: precision bound, tolerance budget, explicit backend pin (if a future filter encodes that). Not for preferences.

Soft

The filter must leave at least min_remaining candidates. If applying it would drop below this threshold, the pipeline skips this filter for this call (logs that it saturated).

min_remaining = 1 is the typical preference shape: “narrow the set when possible, but don’t leave nothing.” Larger values reserve diversity for downstream filters that might further narrow — e.g., a strided-input-preference filter with min_remaining = 2 ensures the subsequent Judge filter still has at least two options to rank empirically.
