Struct GatewayIdGenerator 

pub struct GatewayIdGenerator { /* private fields */ }

Generates sequential, prefixed gateway ids of the form prefix_NNNNNN.

Counting is deterministic: ids advance monotonically from a fixed start, which makes generated ids reproducible across runs.

Implementations

impl GatewayIdGenerator

pub fn deterministic(prefix: impl Into<String>, start: u64) -> Self

Builds a generator that emits ids with the given prefix, starting the counter at start.

pub fn next_id(&mut self) -> Result<String>

Returns the next id and advances the counter, erroring if the counter would overflow u64.

Trait Implementations

impl Clone for GatewayIdGenerator

fn clone(&self) -> GatewayIdGenerator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GatewayIdGenerator

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

Formats the value using the given formatter.

impl Eq for GatewayIdGenerator

impl PartialEq for GatewayIdGenerator

fn eq(&self, other: &GatewayIdGenerator) -> 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.
