Struct eventstore_tcp::StreamVersion

pub struct StreamVersion(_);

StreamVersion represents the valid values for a stream version which is the same as the event number of the latest event. As such, values are non-negative integers up to i32::max_value. Negative values of i32 have special meaning in the protocol, and are restricted from being used with this type.

Conversions to StreamVersion are quite horrible until TryFrom is stabilized.

Methods

impl StreamVersion

fn from(version: u32) -> Self

Converts the value to a StreamVersion or panics if the value is out of range

fn from_opt(version: u32) -> Option<Self>

Converts the value to a StreamVersion returning None if the input is out of range.
