Struct DescriptorBuffer 

pub struct DescriptorBuffer { /* private fields */ }

Row-major descriptor matrix with a fixed width and explicit scalar kind.

Implementations

impl DescriptorBuffer

pub fn try_binary( rows: usize, bytes_per_row: usize, data: Vec<u8>, ) -> VisionResult<Self>

Creates a checked row-major binary descriptor matrix.

pub fn try_float32( rows: usize, values_per_row: usize, data: Vec<f32>, ) -> VisionResult<Self>

Creates a checked row-major float32 descriptor matrix.

pub const fn kind(&self) -> DescriptorKind

Returns the descriptor scalar representation.

pub const fn len(&self) -> usize

Returns the descriptor row count.

pub const fn is_empty(&self) -> bool

Returns whether there are no descriptor rows.

pub const fn width(&self) -> usize

Returns bytes or float values per descriptor.

pub fn binary_row(&self, index: usize) -> Option<&[u8]>

Returns one binary descriptor, or None for a wrong kind or row index.

pub fn float32_row(&self, index: usize) -> Option<&[f32]>

Returns one float descriptor, or None for a wrong kind or row index.

pub fn binary_data(&self) -> Option<&[u8]>

Returns packed binary storage when the descriptor kind is binary.

pub fn float32_data(&self) -> Option<&[f32]>

Returns packed float storage when the descriptor kind is float32.

Trait Implementations

impl Clone for DescriptorBuffer

fn clone(&self) -> DescriptorBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DescriptorBuffer

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

Formats the value using the given formatter.

impl PartialEq for DescriptorBuffer

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