Struct UninitByteArray 

pub struct UninitByteArray { /* private fields */ }

marker struct for uninitialized byte arrays that still require padding information for odd arrays from user. If you wish for a default constructor please check ByteArray::default. Please note that this struct represents an intermediate state and is not to be used by the client directly

Implementations

impl UninitByteArray

pub fn with_capacity(self, byte_size: usize) -> Self

pre initializes the capacity for more efficient pre-allocation this returns an Uninitialized Byte Array and is used in cases where the user wants to override the padding direction with UninitByteArray::with_odd_pad_dir

Note

in cases where the Default odd array padding is sufficient and more efficient please use ByteArray::with_capacity instead

Example

use byte_array_ops::byte_array::model::{ByteArray, ByteArrayOddWordPad};

let arr = ByteArray::new_uninit()
        .with_capacity(20)
        .with_odd_pad_dir(ByteArrayOddWordPad::LeftPadding)
        .with_hex("efab123").expect("failed to convert hex");

// In cases where the default padding is sufficient please use the direct constructor instead
let arr_2 = ByteArray::with_capacity(20)
        .with_hex("efab123").expect("failed to convert");

assert_eq!(arr,arr_2);
assert_eq!(arr_2.as_bytes(),[0x0e,0xfa,0xb1,0x23]);

pub fn with_odd_pad_dir(self, pad_dir: ByteArrayOddWordPad) -> ByteArray

Explicitly sets the padding direction. This is not needed in general and is only provided in cases where padding must be explicitly set for readability purposes. By default, ByteArray uses Left Padding

Warning

Please read documentation of ByteArrayOddWordPad for an understanding of what padding means in this context

Example

use byte_array_ops::byte_array::model::{ByteArray, ByteArrayOddWordPad};
let arr = ByteArray::new_uninit()
        .with_odd_pad_dir(ByteArrayOddWordPad::LeftPadding)
        .with_hex("feab123").expect("failed to convert");

assert_eq!(arr.as_bytes(),[0x0f,0xea,0xb1,0x23]);
