Struct Builder 

pub struct Builder<'a> { /* private fields */ }

A builder to build a Sonyflake generator.

Implementations

impl<'a> Builder<'a>

pub fn new() -> Self

Construct a new builder to call methods on for the Sonyflake construction.

pub fn start_time(self, start_time: DateTime<Utc>) -> Self

Sets the start time. If the time is ahead of current time, finalize will fail.

pub fn machine_id( self, machine_id: &'a dyn Fn() -> Result<u16, Box<dyn StdError + Send + Sync + 'static>>, ) -> Self

Sets the machine id. If the fn returns an error, finalize will fail.

pub fn check_machine_id(self, check_machine_id: &'a dyn Fn(u16) -> bool) -> Self

Set a function to check the machine id. If the fn returns false, finalize will fail.

pub fn finalize(self) -> Result<Sonyflake, Error>

Finalize the builder to create a Sonyflake.

Errors

This function will return an error if there’s a problem with determining the current time. It will also return an error if the machine id fn failed or if the machine id is invalid.
