Struct MultiValueMut 

pub struct MultiValueMut<'borrow> { /* private fields */ }

An intermediate representation of a mutable multivar obtained from a File.

Implementations

impl MultiValueMut<'_>

pub fn get(&self) -> Result<Vec<BString>, Error>

Returns the actual values.

pub fn len(&self) -> usize

Returns the amount of values within this multivar.

pub fn is_empty(&self) -> bool

Returns true if the multivar does not have any values. This might occur if the value was deleted but wasn’t yet set with a new value.

pub fn set_string_at( &mut self, index: usize, value: impl AsRef<str>, ) -> Result<(), Error>

Sets the value at the given index.

Safety

This will panic if the index is out of range.

pub fn set_at(&mut self, index: usize, value: impl AsBStr) -> Result<(), Error>

Sets the value at the given index.

Safety

This will panic if the index is out of range.

pub fn set_values<Iter, Item>(&mut self, values: Iter) -> Result<(), Error>

where Iter: IntoIterator<Item = Item>, Item: AsBStr,

Sets all values to the provided ones. Note that this follows zip logic: if the number of values in the input is less than the number of values currently existing, then only the first n values are modified. If more values are provided than there currently are, then the remaining values are ignored.

pub fn set_all(&mut self, input: impl AsBStr) -> Result<(), Error>

Sets all values in this multivar to the provided one without owning the provided input.

pub fn delete(&mut self, index: usize)

Removes the value at the given index. Does nothing when called multiple times in succession.

Safety

This will panic if the index is out of range.

pub fn delete_all(&mut self)

Removes all values. Does nothing when called multiple times in succession.

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

Formats the value using the given formatter.
