Struct Database 

pub struct Database { /* private fields */ }

A queryable constraint database for a single device.

Implementations

impl Database

pub const fn f446re() -> Database

The hand-verified database for the NUCLEO-F446RE’s STM32F446RE.

pub fn lookup(&self, pin: Pin, af: u8) -> impl Iterator<Item = &AfMapping>

Every mapping for pin at alternate function af.

Returns an iterator because one (pin, AF) can carry several peripheral signals — e.g. on the F446 PA4/AF5 is both SPI1_NSS and I2S1_WS (SPI and I2S share the same hardware block and AF number).

pub fn alt_functions(&self, pin: Pin) -> impl Iterator<Item = &AfMapping>

Every alternate-function mapping available on pin.

pub fn pins(&self) -> Vec<Pin>

Every physical pin that has at least one alternate function, sorted and deduplicated. Used by the LSP to offer pin-name completions.

pub fn find_af(&self, pin: Pin, peripheral: &str, signal: &str) -> Option<u8>

Reverse lookup: the AF number that connects pin to peripheral’s signal, if any. Used by the constraint solver.

Trait Implementations

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

Performs copy-assignment from source.

impl Copy for Database

impl Debug for Database

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

Formats the value using the given formatter.
