Trait format_bytes::DisplayBytes [−][src]
pub trait DisplayBytes {
fn display_bytes(&self, output: &mut dyn Write) -> Result<()>;
}Expand description
Let types decide how to format themselves for presentation to users in a byte-stream output.
Similar to std::fmt::Display, but the output stream is bytes instead of Unicode.
When output is presented to users, it is decoded with an unspecified character encoding that is presumed to be ASCII-compatible.
Implementers should return any error from output (e.g. with the ? operator),
and not emit other errors.
Example
A typical impl for a struct with multiple fields might use the write_bytes macro:
use format_bytes::{DisplayBytes, write_bytes};
struct Point2D { x: f32, y: f32 }
impl DisplayBytes for Point2D {
fn display_bytes(
&self,
out: &mut dyn std::io::Write,
) -> std::io::Result<()> {
write_bytes!(out, b"x = {}, y = {}", self.x, self.y)
}
}Required methods
fn display_bytes(&self, output: &mut dyn Write) -> Result<()>

Format to ASCII bytes with std::fmt::Display.
The Display impl for this type only emits ASCII characters,
so it’s less useful than in the general case
to make users explicitly opt-in to UTF-8 encoding.
