Struct ArrayDimensions

pub struct ArrayDimensions {
    pub size: Option<u32>,
    pub lower_bound: Option<u32>,
}

Represents a single dimension of a multi-dimensional array with optional size and bounds.

In .NET, arrays can have multiple dimensions with configurable lower bounds and sizes. This structure captures the metadata for a single dimension of such an array.

Fields

• size: The number of elements in this dimension (if known at compile time)
• lower_bound: The lowest valid index for this dimension (typically 0)

Examples

use dotscope::metadata::typesystem::ArrayDimensions;

// A dimension with 10 elements starting at index 0
let dim = ArrayDimensions {
    size: Some(10),
    lower_bound: Some(0),
};

// An unbounded dimension (size determined at runtime)
let unbounded = ArrayDimensions {
    size: None,
    lower_bound: Some(1), // 1-based indexing
};

Fields

size: Option<u32>

The size of this dimension (number of elements).

None indicates the size is not fixed at compile time and will be determined at runtime when the array is allocated.

lower_bound: Option<u32>

The lower bound of this dimension (lowest index that can be used to access an element).

Most .NET arrays use 0-based indexing, but the runtime supports arbitrary lower bounds. None typically means the lower bound is 0.

Trait Implementations

impl Clone for ArrayDimensions

fn clone(&self) -> ArrayDimensions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArrayDimensions

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

Formats the value using the given formatter.

impl Default for ArrayDimensions

fn default() -> ArrayDimensions

Returns the “default value” for a type.

impl PartialEq for ArrayDimensions

fn eq(&self, other: &ArrayDimensions) -> 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.
