use sb

StringBuilder - Efficient string building. Avoids O(n²) cost of repeated str::concat.

Functions

fn append_char

Append a single character (by code point).

Signature: (sb:ptr c:i64 -- sb:ptr)

Example:

builder 65 sb::append_char  // builder

fn append_int

Append an integer as string.

Signature: (sb:ptr n:i64 -- sb:ptr)

Example:

builder 42 sb::append_int  // builder

fn append

Append a string to the builder.

Signature: (sb:ptr s:str -- sb:ptr)

Example:

builder "hello" sb::append  // builder

fn build

Build the final string (does not consume builder).

Signature: (sb:ptr -- s:str)

Example:

builder sb::build  // result

fn finish

Build string and free builder in one call.

Signature: (sb:ptr -- s:str)

Example:

builder sb::finish  // result

fn free

Free the builder's resources.

Signature: (sb:ptr -- )

Example:

builder sb::free

fn len

Get current length of builder content.

Signature: (sb:ptr -- sblen:i64)

Example:

builder sb::len  // sblen

fn new

Create a new StringBuilder with default capacity.

Signature: ( -- sb:ptr)

Example:

sb::new  // builder

fn with_capacity

Create a StringBuilder with specific initial capacity.

Signature: (capacity:i64 -- sb:ptr)

Example:

1024 sb::with_capacity  // builder

Growable string buffer for efficient string building.
