Struct HaysonRelationRestrictError 

pub struct HaysonRelationRestrictError {
    pub relation: String,
    pub table: String,
    pub key: String,
    pub referencing_table: String,
    pub referencing_field: String,
    pub referencing: usize,
}

A delete refused because an on_delete: 'restrict' relation still has a live record referencing the key being deleted. referencing is the count of records found still pointing at it — capped at the same sample the diagnostic report uses, never a full scan’s whole count.

Fields

relation: String

table: String

key: String

referencing_table: String

referencing_field: String

referencing: usize
