pub struct BitString { /* private fields */ }
Expand description
Bit-string as defined by the W3C Bitstring Status List specification.
Bits are indexed from most significant to least significant.
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ... | n-8 | n-7 | n-6 | n-5 | n-4 | n-3 | n-2 | n-1 |
| byte 0 | ... | byte k-1 |

Implementations§
Source§impl BitString
impl BitString
Sourcepub fn new(status_size: StatusSize) -> Self
pub fn new(status_size: StatusSize) -> Self
Creates a new empty bit-string.
Sourcepub fn new_with(
status_size: StatusSize,
len: usize,
f: impl FnMut(usize) -> u8,
) -> Result<Self, Overflow>
pub fn new_with( status_size: StatusSize, len: usize, f: impl FnMut(usize) -> u8, ) -> Result<Self, Overflow>
Creates a new bit-string of the given length, using f
to initialize
every status.
The f
function is called with the index of the initialized status.
Sourcepub fn new_with_value(
status_size: StatusSize,
len: usize,
value: u8,
) -> Result<Self, Overflow>
pub fn new_with_value( status_size: StatusSize, len: usize, value: u8, ) -> Result<Self, Overflow>
Creates a new bit-string of the given length, setting every status to the same value.
Sourcepub fn new_zeroed(status_size: StatusSize, len: usize) -> Self
pub fn new_zeroed(status_size: StatusSize, len: usize) -> Self
Creates a new bit-string of the given length, setting every status to 0.
Sourcepub fn with_capacity(status_size: StatusSize, capacity: usize) -> Self
pub fn with_capacity(status_size: StatusSize, capacity: usize) -> Self
Creates a new bit-string with the given status size and capacity (in number of statuses).
Sourcepub fn from_bytes(status_size: StatusSize, bytes: Vec<u8>) -> Self
pub fn from_bytes(status_size: StatusSize, bytes: Vec<u8>) -> Self
Creates a bit-string from a byte array and status size.
Sourcepub fn get(&self, index: usize) -> Option<u8>
pub fn get(&self, index: usize) -> Option<u8>
Returns the value stored in the list at the given index.
Sourcepub fn set(&mut self, index: usize, value: u8) -> Result<u8, Overflow>
pub fn set(&mut self, index: usize, value: u8) -> Result<u8, Overflow>
Sets the value at the given index.
Returns the previous value, or an Overflow
error if either the index
is out of bounds or the value is too large.
Sourcepub fn push(&mut self, value: u8) -> Result<usize, Overflow>
pub fn push(&mut self, value: u8) -> Result<usize, Overflow>
Push a new value into the bit-string.
Returns the index of the newly inserted value in the list,
or an error if the value is too large w.r.t. status_size
.
Sourcepub fn iter(&self) -> BitStringIter<'_> ⓘ
pub fn iter(&self) -> BitStringIter<'_> ⓘ
Returns an iterator over all the statuses stored in this bit-string.
Sourcepub fn encode(&self) -> EncodedList
pub fn encode(&self) -> EncodedList
Encodes the bit-string.
