# go-format
|
||||
|
||||
String formatting package using Rust-style formatting directives.
|
||||
|
||||
Output is generally more visually-friendly than `"fmt"`, while performance is neck-and-neck.
|
||||
|
||||
README is WIP.
|
||||
|
||||
## todos
|
||||
|
||||
- improved verbose printing of number types
|
||||
|
||||
- more test cases
|
||||
|
||||
- improved verbose printing of string ptr types
