Struct FieldDelta 

pub struct FieldDelta {
    pub added: Vec<String>,
    pub removed: Vec<String>,
    pub changed: Vec<String>,
}

Which keys of a document object moved. Only ever describes data.

Fields

added: Vec<String>

Keys present only on the to side.

removed: Vec<String>

Keys present only on the from side.

changed: Vec<String>

Keys present on both sides with different values.

Implementations

impl FieldDelta

pub fn is_empty(&self) -> bool

True when no key moved. A Modified change can legitimately carry an empty delta: bi-temporal validity is not a field, so a record whose valid_from moved while its payload stood still changes with no key changing. Reading emptiness as “nothing happened” would lose exactly that case, which is why temporal exists alongside this.
