Struct BlendSelection 

pub struct BlendSelection {
    pub requested: usize,
    pub applied: Vec<usize>,
    pub rejected: Vec<usize>,
    pub reason: Option<String>,
}

What a blend selection actually achieved.

The kernel can answer a group blend with fewer walls than were asked for — the maximal-valid-subset search drops the edges that cannot co-blend at a shared corner rather than failing outright. This says WHICH, so partial fulfilment is a statement instead of a silence.

Fields

requested: usize

How many edges the caller selected.

applied: Vec<usize>

Indices into that selection that carry a blend wall in the result.

rejected: Vec<usize>

Indices that do not.

reason: Option<String>

Why the whole selection could not be built, when something was dropped.

Implementations

impl BlendSelection

pub fn is_complete(&self) -> bool
