Enum Bitpix 

pub enum Bitpix {
    F64 = -64,
    F32 = -32,
    U8 = 8,
    I16 = 16,
    I32 = 32,
}

The type of the values in an array, from its BITPIX card.

Variants

F64 = -64

Float 64

F32 = -32

Float 32

U8 = 8

Unsigned 8 bit

I16 = 16

Signed 16 bit

I32 = 32

Signed 32 bit

Implementations

impl Bitpix

pub fn byte_size(&self) -> usize

How many bytes one value of this type occupies.

impl Bitpix

pub fn read_be(&self, bytes: &[u8]) -> Option<f64>

Decodes one big-endian array value from the front of bytes, widening it to f64.

Returns None when bytes is shorter than Bitpix::byte_size, so a truncated data section produces a short read rather than a panic.

pub fn value_range(&self) -> Option<(f64, f64)>

The inclusive range of values this type can represent, as f64.

None for the floating point types, which have no meaningful full-scale range to normalise against.

Trait Implementations

impl Clone for Bitpix

fn clone(&self) -> Bitpix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Bitpix

impl Debug for Bitpix

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

impl From<Bitpix> for i64

fn from(value: Bitpix) -> Self

Converts to this type from the input type.

impl PartialEq for Bitpix

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

Inequality operator !=.

impl StructuralPartialEq for Bitpix

impl TryFrom<i64> for Bitpix

type Error = Box<dyn Error + Send + Sync>

The type returned in the event of a conversion error.

fn try_from(value: i64) -> Result<Self, Self::Error>

Performs the conversion.
