Struct StrBytes

Source
#[non_exhaustive]
pub struct StrBytes { /* private fields */ }
Expand description

UTF-8 string byte buffer representation with validation amortization. When StrBytes is constructed from a &str or String, its underlying bytes are assumed to be valid UTF-8. Otherwise, if constructed from a byte source, the construction will be fallible.

Example construction from a &str:

use aws_smithy_types::str_bytes::StrBytes;

let value: StrBytes = "example".into();
assert_eq!("example", value.as_str());
assert_eq!(b"example", &value.as_bytes()[..]);

Example construction from Bytes:

use bytes::Bytes;
use aws_smithy_types::str_bytes::StrBytes;

let bytes = Bytes::from_static(b"example");
let value: StrBytes = bytes.try_into().expect("valid utf-8");
assert_eq!("example", value.as_str());
assert_eq!(b"example", &value.as_bytes()[..]);

Implementations§

Source§

impl StrBytes

Source

pub fn as_bytes(&self) -> &Bytes

Returns the underlying Bytes representation.

Source

pub fn as_str(&self) -> &str

Returns the StrBytes value as a &str.

Source

pub fn try_copy_from_slice(slice: &[u8]) -> Result<Self, Utf8Error>

Tries to create a StrBytes from a slice, or returns a Utf8Error if the slice is not valid UTF-8.

Source
