ArrayDesc

Struct ArrayDesc 

Source
pub struct ArrayDesc<'a> { /* private fields */ }
Expand description

Zero-copy view of a VT_CARRAY array descriptor.

Describes a fixed-size array: its element type, number of dimensions, and bounds for each dimension.

Implementations§

Source§

impl<'a> ArrayDesc<'a>

Source

pub fn element_type(&self) -> i32

Element type descriptor at offset 0x00.

Negative values encode simple VT_* types inline. Non-negative values are offsets into the type descriptor table.

Source

pub fn num_dims(&self) -> u16

Number of array dimensions.

Source

pub fn flags(&self) -> u16

Flags / extra field at offset 0x06.

Source

pub fn bound(&self, index: usize) -> Option<SafeArrayBound>

Returns the bounds for dimension index.

Each bound has a count (number of elements) and a lower bound. Returns None if index >= num_dims or the data is too short.

Source

pub fn size(&self) -> usize

Total size of this descriptor in bytes.
