Struct DecodedMaskSet 

pub struct DecodedMaskSet {
    pub nan: Option<Vec<bool>>,
    pub pos_inf: Option<Vec<bool>>,
    pub neg_inf: Option<Vec<bool>>,
}

Three-kind set of decompressed bitmasks, one entry per mask kind present in the frame. Each Vec<bool> has length n_elements (the descriptor’s shape product). Mirrors the encoder’s [crate::substitute_and_mask::MaskSet] but carries no element-count field — callers get it from the descriptor.

Fields

nan: Option<Vec<bool>>

Positions that held NaN at encode time, or None when the frame carried no NaN mask. For complex dtypes a single bit covers BOTH (real, imag) components — see plans/WIRE_FORMAT.md §6.5.2 for the priority rule.

pos_inf: Option<Vec<bool>>

Positions that held +∞, or None. Never overlaps with nan at the same index (encoder’s priority rule assigns each element to at most one kind).

neg_inf: Option<Vec<bool>>

Positions that held −∞, or None. Never overlaps with nan or pos_inf at the same index.

Implementations

impl DecodedMaskSet
