Struct SchemaDiff 

Source 
pub struct SchemaDiff {
    pub strip_fields: Vec<String>,
    pub inject_defaults: Vec<(String, Value)>,
    pub build_indexes: Vec<(String, IndexConfig)>,
    pub drop_indexes: Vec<String>,
}
Expand description

Result of comparing current schema against a stored fingerprint.

Fields§

§strip_fields: Vec<String>

Fields removed from schema → strip from stored records

§inject_defaults: Vec<(String, Value)>

New fields with @default → inject default value into existing records

§build_indexes: Vec<(String, IndexConfig)>

Fields that gained @indexed → build secondary index entries

§drop_indexes: Vec<String>

Fields that lost @indexed → delete index entries
