Struct DxfClassCollection 

pub struct DxfClassCollection { /* private fields */ }

Collection of DXF class definitions, keyed by DXF name (case-insensitive).

Corresponds to ACadSharp’s DxfClassCollection.

Implementations

impl DxfClassCollection

pub fn new() -> Self

Create an empty class collection

pub fn add_or_update(&mut self, class: DxfClass)

Add a class. If a class with the same DXF name already exists, only its instance count is updated (matching ACadSharp behavior).

pub fn get_by_name(&self, dxf_name: &str) -> Option<&DxfClass>

Get a class by its DXF name (case-insensitive)

pub fn contains(&self, dxf_name: &str) -> bool

Check if a class with the given DXF name exists

pub fn len(&self) -> usize

Number of class definitions

pub fn is_empty(&self) -> bool

Check if the collection is empty

pub fn iter(&self) -> impl Iterator<Item = &DxfClass>

Iterate over all class definitions

pub fn clear(&mut self)

Clear all class definitions

pub fn update_defaults(&mut self)

Populate with default class definitions that AutoCAD expects.

This mirrors ACadSharp’s DxfClassCollection.UpdateDxfClasses().

Trait Implementations

impl Clone for DxfClassCollection

fn clone(&self) -> DxfClassCollection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DxfClassCollection

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

Formats the value using the given formatter.

impl Default for DxfClassCollection

fn default() -> Self

Returns the “default value” for a type.

impl<'a> IntoIterator for &'a DxfClassCollection

type Item = &'a DxfClass

The type of the elements being iterated over.

type IntoIter = Iter<'a, DxfClass>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for DxfClassCollection

fn eq(&self, other: &DxfClassCollection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
