pub struct QueryResult { /* private fields */ }

Defines the result of a query operation on a Model

Implementations

impl QueryResult

pub fn try_get_by<T, I>(&self, index: I) -> Result<T, DbErr>

where T: TryGetable, I: ColIdx,

pub fn try_get_by_nullable<T, I>(&self, index: I) -> Result<T, TryGetError>

where T: TryGetable, I: ColIdx,

Get a value from the query result with an ColIdx

pub fn try_get<T>(&self, pre: &str, col: &str) -> Result<T, DbErr>

where T: TryGetable,

Get a value from the query result with prefixed column name

pub fn try_get_nullable<T>( &self, pre: &str, col: &str, ) -> Result<T, TryGetError>

where T: TryGetable,

Get a value from the query result with prefixed column name

pub fn try_get_by_index<T>(&self, idx: usize) -> Result<T, DbErr>

where T: TryGetable,

pub fn column_names(&self) -> Vec<String>

Retrieves the names of the columns in the result set

pub fn try_as_mysql_row(&self) -> Option<&MySqlRow>

Access the underlying MySqlRow if we use the MySQL backend.

Access the underlying PgRow if we use the Postgres backend.

pub fn try_as_sqlite_row(&self) -> Option<&SqliteRow>

Access the underlying SqliteRow if we use the SQLite backend.

pub fn try_as_mock_row(&self) -> Option<&MockRow>

Access the underlying MockRow if we use a mock.

pub fn try_as_proxy_row(&self) -> Option<&ProxyRow>

Access the underlying ProxyRow if we use a proxy.
