Struct RoofSpec 

pub struct RoofSpec {
    pub roof_type: RoofType,
    pub pitch: Expr,
    pub height: Option<Expr>,
    pub secondary_pitch: Option<Expr>,
    pub overhang: Expr,
    pub ridge_offset: Expr,
    pub fascia_depth: Expr,
    pub tier_height: Option<Expr>,
    pub ridge_axis: Option<Axis>,
}

Expression-valued roof parameters as they appear in the grammar.

The interpreter evaluates every field against the current shape’s context and produces a resolved RoofConfig for the geometry builder. pitch and height are mutually exclusive ways to set the roof’s steepness: when height is Some, the pitch is derived from it and the scope’s half-span at derivation time (CGA byHeight parity), letting mixed-width wings share one ridge line.

Fields

roof_type: RoofType

pitch: Expr

Primary pitch angle in degrees, exclusive range (0°, 90°). Ignored when height is set.

height: Option<Expr>

Absolute roof rise in world units (height= named arg). Overrides pitch when present.

secondary_pitch: Option<Expr>

Secondary pitch in degrees for Gambrel / Mansard.

overhang: Expr

Eave overhang beyond the footprint, world units. Default 0.

ridge_offset: Expr

Ridge offset fraction for Saltbox. Default 0.5.

fascia_depth: Expr

Fascia band depth below each perimeter eave. Default 0.

tier_height: Option<Expr>

Pitch-break height fraction for tiered types.

ridge_axis: Option<Axis>

Forces the ridge to run along the given scope axis (ridge=X / ridge=Z), overriding the default longest-axis heuristic.

Implementations

impl RoofSpec

pub fn new(roof_type: RoofType, pitch: f64) -> Self

Literal spec with defaults matching RoofConfig::new — the programmatic construction path for tests and builders.

Trait Implementations

impl Clone for RoofSpec

fn clone(&self) -> RoofSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RoofSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RoofSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<RoofConfig> for RoofSpec

Wraps every numeric field of a resolved config back into literal expressions — the programmatic bridge for builders that think in numbers.

fn from(c: RoofConfig) -> Self

Converts to this type from the input type.

fn eq(&self, other: &RoofSpec) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for RoofSpec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
