Struct Builder

pub struct Builder(/* private fields */);

This is a growable string builder.

Implementations

impl Builder

pub fn new(size: usize) -> Builder

Return a new Builder with an initial capacity.

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

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");

pub 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");
assert_eq!(builder.len(), 4);

pub 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");
builder.append(' ');
builder.append("a string");
assert_eq!(builder.string().unwrap(), "i am building a string");
