Available on crate feature __sqlite-shared only.

Reads and writes a PerSchema pragma, where a None schema selects main.

Provided Methods

fn get<Row>( schema: Option<&str>, conn: &mut SqliteConnection, ) -> QueryResult<Row>

where Self: ReadPragma, Sqlite: QueryMetadata<Self::SqlType>, Row: FromSqlRow<Self::SqlType, Sqlite>,

Read the first row, returning Error::NotFound if the pragma returns none.

fn get_all<Row>( schema: Option<&str>, conn: &mut SqliteConnection, ) -> QueryResult<Vec<Row>>

where Self: ReadPragma, Sqlite: QueryMetadata<Self::SqlType>, Row: FromSqlRow<Self::SqlType, Sqlite>,

Read every row.

fn set<'a>( argument: impl Into<Self::Argument<'a>>, schema: Option<&str>, conn: &mut SqliteConnection, ) -> QueryResult<()>

where Self: WritePragma,

Assign argument, running the statement to completion without confirming the value SQLite applied.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
