Struct FieldSpec 

pub struct FieldSpec {
    pub name: String,
    pub blade_index: usize,
    pub grade: usize,
    pub sign: i8,
}

A field in a type.

Fields

name: String

Field name (e.g., “x”, “xy”).

blade_index: usize

Blade index this field holds (canonical bitmask form).

grade: usize

Grade of the blade.

sign: i8

Sign relative to canonical blade ordering (+1 or -1).

When a blade is specified in non-canonical order (e.g., “e20” instead of “e02”), this sign captures the parity of the permutation needed to reach canonical form. For example, e20 = -e02, so sign = -1.

This sign is applied during product generation to ensure correct results.
