Mojo trait
Writable
The Writable trait describes how a type is written into a Writer.
You must implement write_to which takes self and a type conforming to
Writer:
struct Point(Writable):
var x: Float64
var y: Float64
fn write_to(self, mut writer: Some[Writer]):
var string = "Point"
# Write a single `Span[Byte]`:
writer.write_bytes(string.as_bytes())
# Pass multiple args that can be converted to a `Span[Byte]`:
writer.write("(", self.x, ", ", self.y, ")")Implemented traits

Aliases
__del__is_trivial
alias __del__is_trivial
A flag (often compiler generated) to indicate whether the implementation of __del__ is trivial.
The implementation of __del__ is considered to be trivial if:
- The struct has a compiler-generated trivial destructor and all its fields
have a trivial
__del__method.
In practice, it means that the __del__ can be considered as no-op.
Methods
write_to
write_to(self: _Self, mut writer: T)
Formats the string representation of this type to the provided Writer.
Args:
- writer (
T): The type conforming toWritable.
