Struct sqlx_core::testing::FixtureSnapshot
source · [−]pub struct FixtureSnapshot<DB> { /* private fields */ }Expand description
A snapshot of the current state of the database.
Can be used to generate an INSERT fixture for populating an empty database,
or in the future it may be possible to generate a fixture from the difference between
two snapshots.
Implementations
sourceimpl<DB: Database> FixtureSnapshot<DB>
impl<DB: Database> FixtureSnapshot<DB>
sourcepub fn additive_fixture(&self) -> Result<Fixture<DB>, FixtureError>
pub fn additive_fixture(&self) -> Result<Fixture<DB>, FixtureError>
Generate a fixture to reproduce this snapshot from an empty database using INSERTs.
Note that this doesn’t take into account any triggers that might modify the data before it’s stored.
The INSERT statements are ordered on a best-effort basis to satisfy any foreign key
constraints (data from tables with no foreign keys are inserted first, then the tables
that reference those tables, and so on).
If a cycle in foreign-key constraints is detected, this returns with an error.
