Trait ToUtf8Bytes 

pub trait ToUtf8Bytes {
    // Required methods
    fn to_utf8bytes(&self) -> Utf8Bytes;
    fn to_compact_utf8bytes(&self) -> Utf8Bytes;
}

Available on crate features alloc or std only.

Converts a value to shared or compact UTF-8 bytes using its fmt::Display implementation.

ToUtf8Bytes::to_utf8bytes returns the default shared Utf8Bytes, which retains heap storage after shrinking. ToUtf8Bytes::to_compact_utf8bytes returns crate::compact::Utf8Bytes, which moves short contents back to inline storage.

Examples

use smol_bytes::ToUtf8Bytes;

assert_eq!(42.to_utf8bytes().as_str(), "42");

Required Methods

fn to_utf8bytes(&self) -> Utf8Bytes

Converts this value to the default shared Utf8Bytes using fmt::Display.

Shared results retain heap storage when they are later shortened. Use ToUtf8Bytes::to_compact_utf8bytes when short results should use inline storage.

fn to_compact_utf8bytes(&self) -> Utf8Bytes

Converts this value to compact crate::compact::Utf8Bytes using fmt::Display.

Compact results use inline storage when their contents fit. Use ToUtf8Bytes::to_utf8bytes when retaining heap storage after shrinking is preferred.

Examples

use smol_bytes::{ToUtf8Bytes, compact};

let value: compact::Utf8Bytes = 42.to_compact_utf8bytes();
assert_eq!(value.as_str(), "42");

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
