Struct InstanceShape 

pub struct InstanceShape {
    pub log_trace_length: usize,
    pub modulus_bits: usize,
    pub collision_resistance: usize,
    pub num_batched_functions: usize,
}

Per-instance shape data not in the protocol params.

Fields

log_trace_length: usize

modulus_bits: usize

Bit-length of the field FRI/WHIR operates over (typically the extension field).

collision_resistance: usize

Collision resistance of the commitment hash, in bits.

num_batched_functions: usize

Number of committed codewords random-linear-combined into a single low-degree-test instance (trace segments, quotient chunks, …). 1 means no batching. Read by the batched-openings proximity term in crate::stark::proven_security_report.
