Trait Implementations

impl<'a> ExtFnValueCursor for ExtFnStrValues<'a>

type Item = str

The type presented by the cursor.

fn get(&self) -> Option<&Self::Item>

Returns the current value part.

fn advance(&mut self) -> Result<(), Error>

Advances the cursor to the next value part if available.

fn is_null(&self) -> bool

Returns if the data value is NULL

fn kind(&self) -> SqlDataTypeKind

Returns the actual catalog type for the argument

fn data_type(&self) -> SqlDataType

Returns the data type for the argument

fn len(&self) -> usize

Returns the total length for the argument

fn next(&mut self) -> Result<Option<&Self::Item>, Error>

Advances the cursor, returning the next value part if available.

fn for_each<F>(self, f: F) -> Result<(), Error>

where Self: Sized, F: FnMut(&Self::Item),

Calls a closure on each element of an iterator.

fn fold<F, U>(self, init: U, f: F) -> Result<U, Error>

where Self: Sized, F: FnMut(U, &Self::Item) -> U,

Consume the cursor, producing a single, final value.

fn collect<U>(self) -> Result<U, Error>

where Self: Sized, U: for<'s> Extend<&'s Self::Item> + Default,

Consume the cursor folding into the given Extend type
