Enum CapType 

pub enum CapType {
    Film,
    Electrolytic,
    Ceramic,
    Tantalum,
}

Capacitor dielectric types with different parasitic characteristics.

Different dielectric materials have different leakage and dielectric absorption properties. Film caps are nearly ideal, while electrolytics have significant leakage and aging effects.

Variants

Film

Film capacitor (polyester, polypropylene, etc.) Negligible leakage, no dielectric absorption. Used in: coupling caps, tone stacks, most pedal applications.

Electrolytic

Electrolytic capacitor (aluminum, tantalum). Significant leakage (typ. 100kΩ-10MΩ parallel resistance). Aging increases leakage. Can exhibit dielectric absorption. Used in: power supply filtering, bias decoupling, large coupling caps.

Ceramic

Ceramic capacitor (X7R, C0G/NP0, Y5V). Low leakage but can have voltage coefficient (capacitance changes with voltage). C0G/NP0 types are stable; X7R/Y5V lose capacitance under DC bias. Used in: HF bypass, decoupling, RF applications.

Tantalum

Tantalum capacitor (solid electrolytic). Better leakage than aluminum electrolytic, smaller size. Used in: compact designs, stable bypass applications.

Trait Implementations

impl Clone for CapType

fn clone(&self) -> CapType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CapType

impl Debug for CapType

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

Formats the value using the given formatter.

impl Default for CapType

fn default() -> CapType

Returns the “default value” for a type.

impl Eq for CapType

impl PartialEq for CapType

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
