Struct LineSegmentVec 

pub struct LineSegmentVec {
    pub run_destructor: bool,
    /* private fields */
}

Fields

run_destructor: bool

Whether to run the destructor on drop (prevents double-free when cloned to C)

Implementations

impl LineSegmentVec

pub fn new() -> LineSegmentVec

pub fn with_capacity(cap: usize) -> Self

pub const fn from_const_slice(input: &'static [LineSegment]) -> Self

pub fn from_vec(input: Vec<LineSegment>) -> Self

pub fn iter(&self) -> Iter<'_, LineSegment>

pub fn ptr_as_usize(&self) -> usize

pub const fn len(&self) -> usize

pub const fn capacity(&self) -> usize

pub const fn is_empty(&self) -> bool

pub fn get(&self, index: usize) -> Option<&LineSegment>

Returns a reference to the element at the given index (Rust-only, inline).

pub fn c_get(&self, index: usize) -> OptionLineSegment

where LineSegment: Clone,

C-API compatible get function. Returns a copy of the element at the given index. Returns None if the index is out of bounds.

pub fn as_slice(&self) -> &[LineSegment]

Returns the vec as a Rust slice (Rust-only, not C-API compatible).

pub fn as_c_slice(&self) -> LineSegmentVecSlice

Returns a C-compatible slice of the entire Vec.

pub fn as_c_slice_range(&self, start: usize, end: usize) -> LineSegmentVecSlice

Returns a C-compatible slice of a range within the Vec. If the range is out of bounds, it is clamped to the valid range.

pub fn as_ptr(&self) -> *const LineSegment

Returns a pointer to the Vec’s data. Use len() to get the number of elements.

impl LineSegmentVec

pub fn from_copy_on_write(input: Cow<'static, [LineSegment]>) -> LineSegmentVec

pub fn from_item(item: LineSegment) -> Self

Creates a Vec containing a single element

pub unsafe fn copy_from_ptr(ptr: *const LineSegment, len: usize) -> Self

Copies elements from a C array pointer into a new Vec.

Safety

• ptr must be valid for reading len elements
• The memory must be properly aligned for $struct_type
• The elements are cloned, so $struct_type must implement Clone

pub fn clone_self(&self) -> Self

NOTE: CLONES the memory if the memory is external or &’static Moves the memory out if the memory is library-allocated

pub fn into_library_owned_vec(self) -> Vec<LineSegment>

NOTE: CLONES the memory if the memory is external or &’static Moves the memory out if the memory is library-allocated

Trait Implementations

impl AsRef<[LineSegment]> for LineSegmentVec

fn as_ref(&self) -> &[LineSegment]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for LineSegmentVec

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineSegmentVec

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

Formats the value using the given formatter.

impl Default for LineSegmentVec

fn default() -> Self

Returns the “default value” for a type.

impl Drop for LineSegmentVec

fn drop(&mut self)

Executes the destructor for this type.

impl From<&'static [LineSegment]> for LineSegmentVec

fn from(input: &'static [LineSegment]) -> LineSegmentVec

Converts to this type from the input type.

impl From<Vec<LineSegment>> for LineSegmentVec

fn from(input: Vec<LineSegment>) -> LineSegmentVec

Converts to this type from the input type.

impl FromIterator<LineSegment> for LineSegmentVec

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = LineSegment>,

Creates a value from an iterator.

impl PartialEq for LineSegmentVec

fn eq(&self, rhs: &Self) -> 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.
