pub struct DataBlock { /* private fields */ }

One data block.

Implementations

impl DataBlock

pub fn new(name: impl Into<Box<str>>) -> Self

Creates an empty block.

pub fn name(&self) -> &str

The block’s name.

pub fn category(&self, name: &str) -> Option<&Category>

One category.

pub fn category_mut(&mut self, name: &str, span: ByteSpan) -> &mut Category

One category, creating it if it is new.

pub fn take_category(&mut self, name: &str) -> Option<Category>

Removes one category and hands it over, keeping the order of the rest.

Moving a category out costs O(items) and copies none of its values.

pub fn categories(&self) -> impl Iterator<Item = &Category>

The categories, in the order the file gave them.

pub fn len(&self) -> usize

The number of categories.

pub fn is_empty(&self) -> bool

Returns true when the block holds no categories.
