Struct Blob 

pub struct Blob<'a> {
    pub kind: String,
    pub fields: Vec<i32>,
    pub payload: &'a [u8],
    pub properties: BTreeMap<String, String>,
}

A blob to be written to a Puffin file.

Examples

use samkhya_core::puffin::Blob;

let payload = b"sketch bytes";
let blob = Blob::new("samkhya.hll-v1", vec![7], payload);
assert_eq!(blob.kind, "samkhya.hll-v1");
assert_eq!(blob.fields, vec![7]);
assert_eq!(blob.payload, payload);

Fields

kind: String

fields: Vec<i32>

payload: &'a [u8]

properties: BTreeMap<String, String>

Implementations

impl<'a> Blob<'a>

pub fn new(kind: impl Into<String>, fields: Vec<i32>, payload: &'a [u8]) -> Self

Build a blob with empty properties. Add metadata afterwards by inserting into blob.properties.

Examples

use samkhya_core::puffin::Blob;

let blob = Blob::new("samkhya.bloom-v1", vec![1, 2], &[0u8, 1, 2, 3]);
assert!(blob.properties.is_empty());
