Struct StampContext 

pub struct StampContext<'a> {
    pub pin_to_mna: &'a dyn Fn(&str) -> Option<usize>,
    pub vsrc_base: usize,
    pub internal_node_base: usize,
    pub sample_rate: f64,
    pub reactive_one_ports: Option<&'a mut Vec<MnaOnePort>>,
}

Context for multi-terminal MNA stamping.

Provides pin-to-MNA-index resolution and pre-allocated vsource indices so components can stamp themselves into the MNA without knowing graph details.

Fields

pin_to_mna: &'a dyn Fn(&str) -> Option<usize>

Resolve a pin name (e.g., “pos”, “neg”, “out”) to its MNA node index. Returns None for pins connected to ground or supply rails.

vsrc_base: usize

Starting vsource index allocated for this component.

internal_node_base: usize

Starting internal MNA node index allocated for this component. Components that declared mna_internal_node_count() > 0 get indices [internal_node_base .. internal_node_base + mna_internal_node_count()).

sample_rate: f64

Sample rate in Hz.

reactive_one_ports: Option<&'a mut Vec<MnaOnePort>>

Reactive one-ports for state-space integration.
