Mojo trait
Writer
A destination for formatted text output.
Writer is implemented by types that can accept UTF-8 formatted text, such
as strings, files, or network sockets. Types implementing Writable write
their output to a Writer.
The core method is write_string(), which accepts a StringSlice for
efficient, allocation-free output. The convenience method write() accepts
multiple Writable arguments.
Example:
struct StringBuilder(Writer):
var s: String
def write_string(mut self, string: StringSlice):
self.s += string
var builder = StringBuilder("")
builder.write("Count: ", 42) # Writes multiple values at once
print(builder.s) # Count: 42Implemented traits
