Struct jlrs::value::Values

pub struct Values<'frame>(_, _, _);

Several values that are allocated consecutively. This can be used in combination with Value::call_values and WithOutput::call_values.

Implementations

impl<'frame> Values<'frame>

pub fn len(self) -> usize

Returns the number of Values in this group.

pub fn value(self, index: usize) -> JlrsResult<Value<'frame, 'static>>

Get a specific Value in this group. Returns an error if the index is out of bounds.

pub fn new<T, V, F>(frame: &mut F, data: V) -> JlrsResult<Self> where
    T: IntoJulia,
    V: AsRef<[T]>,
    F: Frame<'frame>, 

Allocate several values of the same type, this type must implement IntoJulia. The values will be protected from garbage collection inside the frame used to create them. This takes as many slots on the GC stack as values that are allocated.

Returns an error if there is not enough space on the stack.

pub fn new_dyn<'v, V, F>(frame: &mut F, data: V) -> JlrsResult<Self> where
    V: AsRef<[&'v dyn IntoJulia]>,
    F: Frame<'frame>, 

Allocate several values of possibly different types, these types must implement IntoJulia. The values will be protected from garbage collection inside the frame used to create them. This takes as many slots on the GC stack as values that are allocated.

Returns an error if there is not enough space on the stack.

Trait Implementations

impl<'frame> Clone for Values<'frame>

fn clone(&self) -> Values<'frame>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'frame> Copy for Values<'frame>

impl<'frame> Debug for Values<'frame>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
