Struct ConflictContext 

Source 
pub struct ConflictContext { /* private fields */ }
Expand description

Context available to a conflict handler during changeset application.

Wraps the raw sqlite3_changeset_iter to provide safe access to the table name, column count, and column values involved in a conflict.

Implementations§

Source§

impl ConflictContext

Source

pub fn table_name(&self) -> &str

The table name for this conflict’s operation.

Source

pub fn column_count(&self) -> usize

The number of columns in this table.

Source

pub fn new_value(&self, col: usize) -> Option<String>

Get the “new” value for a column (the incoming value from the changeset). Available for DATA and CONSTRAINT conflicts. Returns None if the column was not changed or the value is NULL.

Source

pub fn conflict_value(&self, col: usize) -> Option<String>

Get the “conflict” value for a column (the current local value). Available for DATA and CONFLICT conflicts.

Source

pub fn old_value(&self, col: usize) -> Option<String>

Get the “old” value for a column (the value expected by the changeset). Available for DATA and NOTFOUND conflicts.
