Enum ArrayValues 

#[non_exhaustive]
pub enum ArrayValues {
    F64(Vec<f64>),
    F32(Vec<f32>),
    I64(Vec<i64>),
    I32(Vec<i32>),
    I16(Vec<i16>),
    I8(Vec<i8>),
    U64(Vec<u64>),
    U32(Vec<u32>),
    U16(Vec<u16>),
    U8(Vec<u8>),
}

A block of numbers, in the type the file holds them.

Typed, not converted. A dataset of doubles comes back as Vec<f64>, integers as Vec<i32>, and so on - because the point of reading a million points is to hand them to something that draws them, and every conversion on the way is a copy of the whole array. See ArrayData for the counting.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

F64(Vec<f64>)

H5T_IEEE_F64 and friends.

F32(Vec<f32>)

32-bit floats.

I64(Vec<i64>)

Signed integers, by width.

I32(Vec<i32>)

Signed 32-bit.

I16(Vec<i16>)

Signed 16-bit.

I8(Vec<i8>)

Signed 8-bit.

U64(Vec<u64>)

Unsigned 64-bit.

U32(Vec<u32>)

Unsigned 32-bit.

U16(Vec<u16>)

Unsigned 16-bit.

U8(Vec<u8>)

Unsigned 8-bit, and booleans, which HDF5 stores as bytes.

Implementations

impl ArrayValues

pub fn len(&self) -> usize

How many values there are.

pub fn is_empty(&self) -> bool

Whether there are none.

pub fn to_f64(&self) -> Vec<f64>

The element type, named the way ArrayMetadata names it. Every element widened to f64 - see ArrayData::to_f64, which is this with the shape beside it. This copies.

pub fn element_type(&self) -> &'static str

The element type, named the way ArrayMetadata names it.

pub fn as_bytes(&self) -> &[u8]

The same memory seen as bytes. No copy - a borrow, for a caller about to hand the block to a GPU, a socket or a file.

Trait Implementations

impl Clone for ArrayValues

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 ArrayValues

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

Formats the value using the given formatter.

impl PartialEq for ArrayValues

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

Equality operator ==.

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

Inequality operator !=.
