Struct reql_types::Change

#[non_exhaustive]
pub struct Change<O, N> {
    pub old_val: Option<O>,
    pub new_val: Option<N>,

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct {{ .. }} syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

old_val: Option<O>

new_val: Option<N>

result_type: Option<String>

old_offset: Option<usize>

new_offset: Option<usize>

state: Option<String>
