Struct Str 

pub struct Str(/* private fields */);

Represents an FFI-safe alternative to &str

Has the same requirements as &str, however these requirements may not be met if passed from a foreign callsite, so additional checks may be necessary.

Implementations

impl Str

pub const fn from_str(s: &str) -> Str

Creates a new Str from a string slice.

pub const fn as_bytes(&self) -> &Slice<u8>
