Struct string_builder::Builder

pub struct Builder(_);

This is a growable string builder.

Methods

impl Builder

fn new(size: usize) -> Builder

Return a new Builder with an initial capacity.

fn append<T: ToBytes>(&mut self, buf: T) -> Result<()>

Add a type that can be viewed as a slice of bytes.

Example

use string_builder::Builder;

let mut builder = Builder::default();
builder.append("some string").unwrap();

fn len(&self) -> usize

Return the current length in bytes of the underlying buffer.

Example

use string_builder::Builder;

let mut builder = Builder::default();
builder.append("four").unwrap();
assert_eq!(builder.len(), 4);

fn string(self) -> Result<String, FromUtf8Error>

Return a String of our buffer once we are done appending to it. This method consumes the underlying buffer.

Example

use string_builder::Builder;

let mut builder = Builder::default();
builder.append("i am building").unwrap();
builder.append(' ').unwrap();
builder.append("a string").unwrap();
assert_eq!(builder.string().unwrap(), "i am building a string");
