Struct puff_rs::types::bytes_builder::BytesBuilder

pub struct BytesBuilder(_);

Fast Byte Buffer

Puff’s BytesBuilder type uses std::vec::Vec under the hood. Vecs are not sharable structures and so need to be wrapped in an Arc to be shared between threads and cheaply copied. You should use a BytesBuilder and convert it into Bytes when you are done writing to it.

Examples

use puff_rs::types::BytesBuilder;

let mut builder = BytesBuilder::new();
builder.put("hello_world");
let bytes = builder.into_bytes();

Implementations

impl BytesBuilder

pub fn new() -> Self

Creates an empty BytesBuilder.

The hash map is initially created with a capacity of 0, so it will not allocate until it is first inserted into.

Examples

use puff_rs::types::{Text, BytesBuilder};
let mut builder = BytesBuilder::new();

pub fn with_capacity(capacity: usize) -> Self

Creates an empty BytesBuilder with the specified capacity.

The buffer will be able to hold at least capacity elements without reallocating. If capacity is 0, the hash map will not allocate.

Examples

use puff_rs::types::BytesBuilder;
let mut builder = BytesBuilder::with_capacity(10);

pub fn put<T: Into<Bytes>>(&mut self, slice: T)

Puts some bytes into the builder.

Examples

use puff_rs::types::BytesBuilder;
let mut builder = BytesBuilder::new();
builder.put("Hi");

pub fn put_slice(&mut self, slice: &[u8])

Puts a slice into the builder.

Examples

use puff_rs::types::BytesBuilder;
let mut builder = BytesBuilder::new();
builder.put_slice("Hi".as_bytes());

pub fn into_bytes(self) -> Bytes

Converts BytesBuilder into Bytes.
