Struct Blob 

pub struct Blob { /* private fields */ }

Raw data attached to a point

ARMS stores this opaquely. You define what it means.

Implementations

impl Blob

pub fn new(data: Vec<u8>) -> Self

Create a new blob from bytes

Example

use arms::Blob;
let blob = Blob::new(vec![1, 2, 3, 4]);
assert_eq!(blob.size(), 4);

pub fn empty() -> Self

Create an empty blob

Useful when you only care about position, not payload.

pub fn from_str(s: &str) -> Self

Create a blob from a string (UTF-8 bytes)

Example

use arms::Blob;
let blob = Blob::from_str("hello");
assert_eq!(blob.as_str(), Some("hello"));

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

Get the raw bytes

pub fn size(&self) -> usize

Get the size in bytes

pub fn is_empty(&self) -> bool

Check if the blob is empty

pub fn as_str(&self) -> Option<&str>

Try to interpret as UTF-8 string

pub fn into_inner(self) -> Vec<u8>

Consume and return the inner data

Trait Implementations

impl Clone for Blob

fn clone(&self) -> Blob

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Blob

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

Formats the value using the given formatter.

impl From<&[u8]> for Blob

fn from(data: &[u8]) -> Self

Converts to this type from the input type.

impl From<&str> for Blob

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for Blob

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for Blob

fn from(data: Vec<u8>) -> Self

Converts to this type from the input type.

impl PartialEq for Blob

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