Struct TableQueryWrapper

pub struct TableQueryWrapper { /* private fields */ }

Simple wrapper for building conditions.

Implementations

impl TableQueryWrapper

pub fn column_equal_to_xdr( &mut self, column: impl ToString, xdr: &impl WriteXdr, ) -> &mut Self

Adds a new condition in the update according to which a given column should be equal to an XDR object.

pub fn column_equal_to_bytes( &mut self, column: impl ToString, bytes: &[u8], ) -> &mut Self

Adds a new condition in the update according to which a given column should be equal to the matching bytes array.

This filter should be used when dealing with non-XDR types. Serialization must be carried by the implementor.

pub fn column_equal_to<T: Serialize + TryInto<ZephyrVal>>( &mut self, column: impl ToString, argument: T, ) -> &mut Self

Adds a new condition in the update according to which a given column should be equal to the matching object.

Under the hood, the object is converted to a ZephyrVal and is later serialized.

pub fn column_gt_xdr( &mut self, column: impl ToString, xdr: &impl WriteXdr, ) -> &mut Self

Adds a new condition in the update according to which a given column should be greater than an XDR object.

pub fn column_gt_bytes( &mut self, column: impl ToString, bytes: &[u8], ) -> &mut Self

Adds a new condition in the update according to which a given column should be greater than the matching bytes array.

This filter should be used when dealing with non-XDR types. Serialization must be carried by the implementor.

pub fn column_gt<T: Serialize + TryInto<ZephyrVal>>( &mut self, column: impl ToString, argument: T, ) -> &mut Self

Adds a new condition in the update according to which a given column should be greater than the matching object.

Under the hood, the object is converted to a ZephyrVal and is later serialized.

pub fn column_lt_xdr( &mut self, column: impl ToString, xdr: &impl WriteXdr, ) -> &mut Self

Adds a new condition in the update according to which a given column should be less than an XDR object.

pub fn column_lt_bytes( &mut self, column: impl ToString, bytes: &[u8], ) -> &mut Self

Adds a new condition in the update according to which a given column should be less than the matching bytes array.

This filter should be used when dealing with non-XDR types. Serialization must be carried by the implementor.

pub fn column_lt<T: Serialize + TryInto<ZephyrVal>>( &mut self, column: impl ToString, argument: T, ) -> &mut Self

Adds a new condition in the update according to which a given column should be less than the matching object.

Under the hood, the object is converted to a ZephyrVal and is later serialized.

pub fn execute( &mut self, interact: &impl DatabaseInteract, ) -> Result<(), SdkError>

Executes the update. Note: should only be used when updating a table.

pub fn read<T: DatabaseInteract>(&self) -> Result<Vec<T>, SdkError>

Executes the query and returns the results.
