Enum FocalPlane 

pub enum FocalPlane {
    First,
    Second,
}

Which focal plane the reticle is etched in.

Serialized as "ffp" / "sfp" — the spellings every optics catalog and every shooter uses, rather than the Rust variant names.

Variants

First

First focal plane: subtensions are constant at every magnification.

Second

Second focal plane: subtensions scale as reference_magnification / magnification.

Implementations

impl FocalPlane

pub fn label(self) -> &'static str

"FFP" / "SFP", for tables and help text.

pub fn is_magnification_dependent(self) -> bool

True when mark subtensions depend on magnification.
