Struct CallsignGenerator 

pub struct CallsignGenerator { /* private fields */ }

Callsign generator with collision avoidance.

Tracks used callsigns to ensure uniqueness within a mesh.

Implementations

impl CallsignGenerator

pub fn new() -> CallsignGenerator

Create a new callsign generator.

pub fn generate(&mut self) -> Result<String, CallsignError>

Generate a random unused callsign.

Returns Err(CallsignError::Exhausted) if all 2,600 callsigns are in use.

pub fn reserve(&mut self, callsign: &str) -> Result<(), CallsignError>

Reserve a specific callsign for manual assignment.

Returns Ok(()) if the callsign was successfully reserved. Returns Err if the callsign is invalid or already in use.

pub fn release(&mut self, callsign: &str) -> bool

Release a callsign for reuse.

Returns true if the callsign was found and released.

pub fn is_available(&self, callsign: &str) -> bool

Check if a callsign is available.

pub fn is_valid_format(callsign: &str) -> bool

Check if a callsign has valid format.

Valid format: {NATO_WORD}-{NN} where NN is 00-99.

pub fn parse(callsign: &str) -> Option<(usize, u8)>

Parse a callsign into (letter_index, number).

Returns None if the format is invalid.

pub fn used_count(&self) -> usize

Get count of used callsigns.

pub fn available_count(&self) -> usize

Get count of available callsigns.
