Struct FitsHeaderKeyword 

pub struct FitsHeaderKeyword { /* private fields */ }

Available on crate feature fits only.

A FITS header keyword. This wrapper provides functions to interact with both raw arrays and strings.

Examples

use astro_rs::fits::FitsHeaderKeyword;

let simple_keyword = FitsHeaderKeyword::from(*b"SIMPLE  ");
assert!(simple_keyword == "SIMPLE");
assert!(simple_keyword == *b"SIMPLE  ");

assert!(simple_keyword != "BITPIX");
assert!(simple_keyword != *b"BITPIX  ");

Implementations

impl FitsHeaderKeyword

pub fn append_number(&mut self, number: u16)

Appends the given number to the keyword. If a number is already appended, it is replaced by the given number.

Examples

use astro_rs::fits::*;

let mut naxis_keyword = FitsHeaderKeyword::from(NAXIS_KEYWORD);
naxis_keyword.append_number(1);
assert_eq!(naxis_keyword, "NAXIS1");
naxis_keyword.append_number(2);
assert_eq!(naxis_keyword, "NAXIS2");

let mut tform_keyword = FitsHeaderKeyword::from(TFORM_KEYWORD);
tform_keyword.append_number(100);
assert_eq!(tform_keyword, "TFORM100");
tform_keyword.append_number(10);
assert_eq!(tform_keyword, "TFORM10");

impl PartialEq<&str> for FitsHeaderKeyword

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